FindLua
-------
+Finds the Lua library:
+.. code-block:: cmake
-Locate Lua library.
+ find_package(Lua [<version>] [...])
-This module defines::
+Lua is a embeddable scripting language.
-::
+.. versionadded:: 3.18
+ Support for Lua 5.4.
- LUA_FOUND - if false, do not try to link to Lua
- LUA_LIBRARIES - both lua and lualib
- LUA_INCLUDE_DIR - where to find lua.h
- LUA_VERSION_STRING - the version of Lua found
- LUA_VERSION_MAJOR - the major version of Lua
- LUA_VERSION_MINOR - the minor version of Lua
- LUA_VERSION_PATCH - the patch version of Lua
+.. versionadded:: 4.3
+ Support for Lua 5.5.
+When working with Lua, its library headers are intended to be included in
+project source code as:
+.. code-block:: c
-Note that the expected include convention is
+ #include <lua.h>
-::
+and not:
- #include "lua.h"
+.. code-block:: c
-and not
+ #include <lua/lua.h>
-::
+This is because, the location of Lua headers may differ across platforms and may
+exist in locations other than ``lua/``.
- #include <lua/lua.h>
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module defines the following variables:
+
+``Lua_FOUND``
+ .. versionadded:: 3.3
+
+ Boolean indicating whether (the requested version of) Lua was found.
+
+``Lua_VERSION``
+ .. versionadded:: 4.2
+
+ The version of Lua found.
+
+``Lua_VERSION_MAJOR``
+ .. versionadded:: 4.2
+
+ The major version of Lua found.
+
+``Lua_VERSION_MINOR``
+ .. versionadded:: 4.2
+
+ The minor version of Lua found.
+
+``Lua_VERSION_PATCH``
+ .. versionadded:: 4.2
+
+ The patch version of Lua found.
+
+``LUA_LIBRARIES``
+ Libraries needed to link against to use Lua. This list includes both ``lua``
+ and ``lualib`` libraries.
+
+Cache Variables
+^^^^^^^^^^^^^^^
+
+The following cache variables may also be set:
+
+``LUA_INCLUDE_DIR``
+ The directory containing the Lua header files, such as ``lua.h``,
+ ``lualib.h``, and ``lauxlib.h``, needed to use Lua.
+
+Deprecated Variables
+^^^^^^^^^^^^^^^^^^^^
+
+The following variables are provided for backward compatibility:
-This is because, the lua location is not standardized and may exist in
-locations other than lua/
+``LUA_FOUND``
+ .. deprecated:: 4.2
+ Use ``Lua_FOUND``, which has the same value.
+
+ Boolean indicating whether (the requested version of) Lua was found.
+
+``LUA_VERSION_STRING``
+ .. deprecated:: 4.2
+ Superseded by the ``Lua_VERSION``.
+
+ The version of Lua found.
+
+``LUA_VERSION_MAJOR``
+ .. deprecated:: 4.2
+ Superseded by the ``Lua_VERSION_MAJOR``.
+
+ The major version of Lua found.
+
+``LUA_VERSION_MINOR``
+ .. deprecated:: 4.2
+ Superseded by the ``Lua_VERSION_MINOR``.
+
+ The minor version of Lua found.
+
+``LUA_VERSION_PATCH``
+ .. deprecated:: 4.2
+ Superseded by the ``Lua_VERSION_PATCH``.
+
+ The patch version of Lua found.
+
+Examples
+^^^^^^^^
+
+Finding the Lua library and creating an interface :ref:`imported target
+<Imported Targets>` that encapsulates its usage requirements for linking to a
+project target:
+
+.. code-block:: cmake
+
+ find_package(Lua)
+
+ if(Lua_FOUND AND NOT TARGET Lua::Lua)
+ add_library(Lua::Lua INTERFACE IMPORTED)
+ set_target_properties(
+ Lua::Lua
+ PROPERTIES
+ INTERFACE_INCLUDE_DIRECTORIES "${LUA_INCLUDE_DIR}"
+ INTERFACE_LINK_LIBRARIES "${LUA_LIBRARIES}"
+ )
+ endif()
