+
+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
