+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
+
+#]=======================================================================]

+# in the FIND_PATH() and FIND_LIBRARY() calls
