Subject: [PATCH 2/2] cmake: Use GNUInstallDirs for libdir and includedir

The comon practice in cmake to allow to specify the libdir or
includedir using GNUInstallDirs which introduces the following
options:

* CMAKE_INSTALL_INCLUDEDIR
* CMAKE_INSTALL_LIBDIR

The main motivation behind this change is ability to use /usr/lib64
instead of /usr/lib as a libdir.
