FindFontconfig
--------------
Find Fontconfig headers and library.
Imported Targets
^^^^^^^^^^^^^^^^
``Fontconfig::Fontconfig``
The Fontconfig library, if found.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables in your project:
``FONTCONFIG_FOUND``
true if (the requested version of) Fontconfig is available.
``FONTCONFIG_VERSION``
the version of Fontconfig.
``FONTCONFIG_LIBRARIES``
the libraries to link against to use Fontconfig.
``FONTCONFIG_INCLUDE_DIRS``
where to find the Fontconfig headers.
``FONTCONFIG_COMPILE_OPTIONS``
this should be passed to target_compile_options(), if the
target is not used for linking
#]=======================================================================]
# use pkg-config to get the directories and then use these values
# in the FIND_PATH() and FIND_LIBRARY() calls
