+These are the instructions for installing KDSingleApplication using the CMake buildsystem.
+CMake version 3.12 or higher is required.
+
+Qt Version support:
+ * Qt5 and Qt6 is supported
+
+Also note that the code requires a C++14 compliant compiler,
+
+Please see the comments at the top of CMakeLists.txt for
+the available configuration options you can pass to cmake.
+
+The installation directory defaults to C:/Program Files (x86)/KDSingleApplication on Windows
+(you'll need admin privileges) and /usr/local on non-Windows.  You can change this
+location by passing the option -DCMAKE_INSTALL_PREFIX=/install/path to cmake.
+
+1) From the top directory of your KDSingleApplication installation create a build directory:
+
+     mkdir build
+
+   and change directory into that build directory:
+
+     cd build
+
+2) Now run 'cmake' depending on the kind of build one of the following:
+     cmake -DCMAKE_BUILD_TYPE=Debug ..
+     cmake -DCMAKE_BUILD_TYPE=Release ..
+     cmake -DKDSingleApplication_STATIC=True -DCMAKE_BUILD_TYPE=Debug ..
+     cmake -DKDSingleApplication_STATIC=True -DCMAKE_BUILD_TYPE=Release ..
+
+   To define the install-location use for example:
+     cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=C:/KDAB/kdsingleapplication ..
+     cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=/opt/kdsingleapplication ..
+
+3) Unix
+
+   set your LD_LIBRARY_PATH to point to your KDSingleApplication installation lib directory.
+
+   If you do not have LD_LIBRARY_PATH set already, then in your terminal run:
+    % LD_LIBRARY_PATH=/path/to/kdsingleapplication/lib:$LD_LIBRARY_PATH
+    % export LD_LIBRARY_PATH
+
+   The above must be added into your .bashrc or similar to remain. It may also of course
+   be run from a shell just before building software using KDSingleApplication, but in this case
+   your settings will only be available for this shell.
+
+4) MacOS
+
+   Proceed as described above, but using DYLD_LIBRARY_PATH instead of LD_LIBRARY_PATH
+
+5) Windows
+
+   For running executables, add the path to the KDSingleApplication dll (kdsingleapplication\bin) into your PATH.
+   eg. set PATH=C:\KDAB\kdsingleapplication\bin;%PATH%
+
+   For development, add the path to the KDSingleApplication lib (kdsingleapplication\lib) into your LIB environment.
+   eg. set LIB=C:\KDAB\kdsingleapplication\lib;%LIB%
+
+6) Build everything by typing:
+
+   From your top-level KDSingleApplication directory run:
+
+   % make    # Unix, Mac
+   % nmake   # Windows
+
+7) (optionally:) Install KDSingleApplication:
+
+   From your top-level KDSingleApplication directory run:
+
+   % make install   # Unix, Mac
+   % nmake install  # Windows
+
+   This will copy the necessary files into the sub-directories of your installation path:
+   For Unix/Linux, Mac: /usr/local
+   For Windows this is: C:\Program Files (x86)\KDSingleApplication
+
+8) Have a look at the examples applications. They will get you started with KDSingleApplication.
+
+== Testing ==
+To build the testing harness, pass -DKDSingleApplication_TESTS=true to CMake, like so:
+  % cmake -DKDSingleApplication_TESTS=true
+
+Then run 'make test' to run the unit tests.
+
+== Using ==
+From your CMake project, add
+
+    find_package(KDSingleApplication CONFIG REQUIRED)
+
+or for Qt6
+
+    find_package(KDSingleApplication-qt6 CONFIG REQUIRED)
+
+and link to the imported target KDAB::kdsingleapplication.
+That's all you need to do (the imported target also brings in the include directories)
+
+You may also need to point the CMAKE_PREFIX_PATH environment variable depending
+on where you installed KDSingleApplication.

+# KDSingleApplication
+
+`KDSingleApplication` is a helper class for single-instance policy applications
+written by [KDAB](https://www.kdab.com).
+
+## Usage
+
+Currently the documentation is woefully lacking, but see the examples or tests
+for inspiration. Basically it involves:
+
+1. Create a `Q(Core|Gui)Application` object.
+2. Create a `KDSingleApplication` object.
+3. Check if the current instance is *primary* (or "master") or
+   *secondary* (or "slave") by calling `isPrimaryInstance`:
+    * the *primary* instance needs to listen from messages coming from the
+      secondary instances, by connecting a slot to the `messageReceived` signal;
+    * the *secondary* instances can send messages to the primary instance
+      by calling `sendMessage`.
+
+See [INSTALL.txt](INSTALL.txt) for installation instructions using CMake.

+generated which are redirects to the first header file.
+The file locations of these generated headers will be stored in
+<camelcase_forwarding_headers_var>.
+
+``ORIGINAL`` specifies how the name of the original header is written: lowercased
+or also camelcased.  The default is "LOWERCASE". Since 1.8.0.
+
+``HEADER_EXTENSION`` specifies what file name extension is used for the header
+files.  The default is "h". Since 5.48.0.
+
+``PREFIX`` places the generated headers in subdirectories.  This should be a
+CamelCase name like ``KParts``, which will cause the CamelCase forwarding
+headers to be placed in the ``KParts`` directory (e.g. ``KParts/Part``).  It
+will also, for the convenience of code in the source distribution, generate
+forwarding headers based on the original names (e.g. ``kparts/part.h``).  This
+allows includes like ``"#include <kparts/part.h>"`` to be used before
+installation, as long as the include_directories are set appropriately.
+
+``OUTPUT_DIR`` specifies where the files will be generated; this should be within
+the build directory. By default, ``${CMAKE_CURRENT_BINARY_DIR}`` will be used.
+This option can be used to avoid file conflicts.
+
+``REQUIRED_HEADERS`` specifies an output variable name where all the required
+headers will be appended so that they can be installed together with the
+generated ones.  This is mostly intended as a convenience so that adding a new
+header to a project only requires specifying the CamelCase variant in the
+CMakeLists.txt file; the original variant will then be added to this
+variable.
+
+``COMMON_HEADER`` generates an additional convenience header which includes all
+other header files.
+
+The ``RELATIVE`` argument indicates where the original headers can be found
+relative to ``CMAKE_CURRENT_SOURCE_DIR``.  It does not affect the generated
+CamelCase forwarding files, but ``ecm_generate_headers()`` uses it when checking
+that the original header exists, and to generate originally named forwarding
+headers when ``PREFIX`` is set.
+
+To allow other parts of the source distribution (eg: tests) to use the
+generated headers before installation, it may be desirable to set the
+``INCLUDE_DIRECTORIES`` property for the library target to output_dir.  For
+example, if ``OUTPUT_DIR`` is ``CMAKE_CURRENT_BINARY_DIR`` (the default), you could do
+
+.. code-block:: cmake
+
+  target_include_directories(MyLib PUBLIC "$<BUILD_INTERFACE:${CMAKE_CURRENT_BINARY_DIR}>")
+
+Example usage (without ``PREFIX``):
+
+.. code-block:: cmake
+
+  ecm_generate_headers(
+      MyLib_FORWARDING_HEADERS
+      HEADERS
+          MLFoo
+          MLBar
+          # etc
+      REQUIRED_HEADERS MyLib_HEADERS

+  )
+  install(FILES ${MyLib_FORWARDING_HEADERS} ${MyLib_HEADERS}
+          DESTINATION ${CMAKE_INSTALL_PREFIX}/include
+          COMPONENT Devel)
+
+Example usage (with ``PREFIX``):
+
+.. code-block:: cmake
+
+  ecm_generate_headers(
+      MyLib_FORWARDING_HEADERS
+      HEADERS
+          Foo

+ECMGeneratePriFile
+------------------
+
+Generate a ``.pri`` file for the benefit of qmake-based projects.
+
+As well as the function below, this module creates the cache variable
+``ECM_MKSPECS_INSTALL_DIR`` and sets the default value to ``mkspecs/modules``.
+This assumes Qt and the current project are both installed to the same
+non-system prefix.  Packagers who use ``-DCMAKE_INSTALL_PREFIX=/usr`` will
+certainly want to set ``ECM_MKSPECS_INSTALL_DIR`` to something like
+``share/qt5/mkspecs/modules``.
+
+The main thing is that this should be the ``modules`` subdirectory of either
+the default qmake ``mkspecs`` directory or of a directory that will be in the
+``$QMAKEPATH`` environment variable when qmake is run.
+
+::
+
+  ecm_generate_pri_file(BASE_NAME <baseName>
+                        LIB_NAME <libName>
+                        [VERSION <version>] # since 5.83
+                        [DEPS "<dep> [<dep> [...]]"]
+                        [FILENAME_VAR <filename_variable>]
+                        [INCLUDE_INSTALL_DIRS <dir> [<dir> [...]]]  # since 5.92
+                        [INCLUDE_INSTALL_DIR <dir>] # deprecated since 5.92
+                        [LIB_INSTALL_DIR <dir>])
+
+If your CMake project produces a Qt-based library, you may expect there to be
+applications that wish to use it that use a qmake-based build system, rather
+than a CMake-based one.  Creating a ``.pri`` file will make use of your
+library convenient for them, in much the same way that CMake config files make
+things convenient for CMake-based applications. ``ecm_generate_pri_file()``
+generates just such a file.
+
+``VERSION`` specifies the version of the library the ``.pri`` file describes. If
+not set, the value is taken from the context variable ``PROJECT_VERSION``.
+This variable is usually set by the ``project(... VERSION ...)`` command or,
+if CMake policy CMP0048 is not ``NEW``, by :module:`ECMSetupVersion`.
+For backward-compatibility with older ECM versions the
+``PROJECT_VERSION_STRING`` variable as set by :module:`ECMSetupVersion`
+will be preferred over ``PROJECT_VERSION`` if set, unless the minimum
+required version of ECM is 5.83 and newer. Since 5.83.
+
+``BASE_NAME`` specifies the name qmake project (.pro) files should use to refer to
+the library (eg: KArchive).  ``LIB_NAME`` is the name of the actual library to
+link to (ie: the first argument to add_library()).  ``DEPS`` is a space-separated
+list of the base names of other libraries (for Qt libraries, use the same
+names you use with the ``QT`` variable in a qmake project file, such as "core"
+for QtCore).  ``FILENAME_VAR`` specifies the name of a variable to store the path
+to the generated file in.
+
+``INCLUDE_INSTALL_DIRS`` are the paths (relative to ``CMAKE_INSTALL_PREFIX``) that
+include files will be installed to. It defaults to
+``${INCLUDE_INSTALL_DIR}/<baseName>`` if the ``INCLUDE_INSTALL_DIR`` variable
+is set. If that variable is not set, the ``CMAKE_INSTALL_INCLUDEDIR`` variable
+is used instead, and if neither are set ``include`` is used.  ``LIB_INSTALL_DIR``
+operates similarly for the installation location for libraries; it defaults to
+``${LIB_INSTALL_DIR}``, ``${CMAKE_INSTALL_LIBDIR}`` or ``lib``, in that order.
+
+``INCLUDE_INSTALL_DIR`` is the old variant of ``INCLUDE_INSTALL_DIRS``, taking only one
+directory.
+
+Example usage:
+
+.. code-block:: cmake
+
+  ecm_generate_pri_file(
+      BASE_NAME KArchive
+      LIB_NAME KF5KArchive
+      DEPS "core"
+      FILENAME_VAR pri_filename
+      VERSION 4.2.0
+  )
+  install(FILES ${pri_filename} DESTINATION ${ECM_MKSPECS_INSTALL_DIR})
+
+A qmake-based project that wished to use this would then do::
+
+  QT += KArchive
+
+in their ``.pro`` file.
+
+Since pre-1.0.0.

+ECMQueryQt
+---------------
+This module can be used to query the installation paths used by Qt.
+
+For Qt5 this uses ``qmake``, and for Qt6 this used ``qtpaths`` (the latter has built-in
+support to query the paths of a target platform when cross-compiling).
+
+This module defines the following function:
+::
+
+    ecm_query_qt(<result_variable> <qt_variable> [TRY])
+
+Passing ``TRY`` will result in the method not making the build fail if the executable
+used for querying has not been found, but instead simply print a warning message and
+return an empty string.
+
+Example usage:
+
+.. code-block:: cmake

+ECMSetupVersion
+---------------
+
+Handle library version information.
+
+::
+
+  ecm_setup_version(<version>
+                    VARIABLE_PREFIX <prefix>
+                    [SOVERSION <soversion>]
+                    [VERSION_HEADER <filename>]
+                    [PACKAGE_VERSION_FILE <filename> [COMPATIBILITY <compat>]] )
+
+This parses a version string and sets up a standard set of version variables.
+It can optionally also create a C version header file and a CMake package
+version file to install along with the library.
+
+If the ``<version>`` argument is of the form ``<major>.<minor>.<patch>``
+(or ``<major>.<minor>.<patch>.<tweak>``), The following CMake variables are
+set::
+
+  <prefix>_VERSION_MAJOR  - <major>
+  <prefix>_VERSION_MINOR  - <minor>
+  <prefix>_VERSION_PATCH  - <patch>
+  <prefix>_VERSION        - <version>
+  <prefix>_SOVERSION      - <soversion>, or <major> if SOVERSION was not given
+
+For backward-compatibility also this variable is set (only if the minimum required
+version of ECM is < 5.83)::
+
+  <prefix>_VERSION_STRING - <version> (use <prefix>_VERSION instead)
+
+If CMake policy CMP0048 is not ``NEW``, the following CMake variables will also
+be set::
+
+  PROJECT_VERSION_MAJOR   - <major>
+  PROJECT_VERSION_MINOR   - <minor>
+  PROJECT_VERSION_PATCH   - <patch>
+  PROJECT_VERSION         - <version>
+
+For backward-compatibility, if CMake policy CMP0048 is not ``NEW``, also this variable is set
+(only if the minimum required version of ECM is < 5.83)::
+
+  PROJECT_VERSION_STRING  - <version> (use PROJECT_VERSION instead)
+
+If the ``VERSION_HEADER`` option is used, a simple C header is generated with the
+given filename. If filename is a relative path, it is interpreted as relative
+to ``CMAKE_CURRENT_BINARY_DIR``.  The generated header contains the following
+macros::
+
+   <prefix>_VERSION_MAJOR  - <major> as an integer
+   <prefix>_VERSION_MINOR  - <minor> as an integer
+   <prefix>_VERSION_PATCH  - <patch> as an integer
+   <prefix>_VERSION_STRING - <version> as a C string
+   <prefix>_VERSION        - the version as an integer
+
+``<prefix>_VERSION`` has ``<patch>`` in the bottom 8 bits, ``<minor>`` in the
+next 8 bits and ``<major>`` in the remaining bits.  Note that ``<patch>`` and
+``<minor>`` must be less than 256.
+
+If the ``PACKAGE_VERSION_FILE`` option is used, a simple CMake package version
+file is created using the ``write_basic_package_version_file()`` macro provided by
+CMake. It should be installed in the same location as the Config.cmake file of
+the library so that it can be found by ``find_package()``.  If the filename is a
+relative path, it is interpreted as relative to ``CMAKE_CURRENT_BINARY_DIR``. The
+optional ``COMPATIBILITY`` option is forwarded to
+``write_basic_package_version_file()``, and defaults to ``AnyNewerVersion``.
+
+If CMake policy CMP0048 is ``NEW``, an alternative form of the command is
+available::
+
+  ecm_setup_version(PROJECT
+                    [VARIABLE_PREFIX <prefix>]
+                    [SOVERSION <soversion>]
+                    [VERSION_HEADER <filename>]
+                    [PACKAGE_VERSION_FILE <filename>] )
+
+This will use the version information set by the ``project()`` command.
+``VARIABLE_PREFIX`` defaults to the project name.  Note that ``PROJECT`` must be the
+first argument.  In all other respects, it behaves like the other form of the
+command.
+
+Since pre-1.0.0.
+
+``COMPATIBILITY`` option available since 1.6.0.

+ECMUninstallTarget
+------------------
+
+Add an ``uninstall`` target.
+
+By including this module, an ``uninstall`` target will be added to your CMake
+project. This will remove all files installed (or updated) by a previous
+invocation of the ``install`` target. It will not remove files created or
+modified by an ``install(SCRIPT)`` or ``install(CODE)`` command; you should
+create a custom uninstallation target for these and use ``add_dependency`` to
+make the ``uninstall`` target depend on it:
+
+.. code-block:: cmake
+
+  include(ECMUninstallTarget)
+  install(SCRIPT install-foo.cmake)
+  add_custom_target(uninstall_foo COMMAND ${CMAKE_COMMAND} -P uninstall-foo.cmake)
+  add_dependency(uninstall uninstall_foo)
+
+The target will fail if the ``install`` target has not yet been run (so it is
+not possible to run CMake on the project and then immediately run the
+``uninstall`` target).
+
+.. warning::
+
+  CMake deliberately does not provide an ``uninstall`` target by default on
+  the basis that such a target has the potential to remove important files
+  from a user's computer. Use with caution.
+
+Since 1.7.0.
