+FindFontconfig
+--------------
+
+Try to find Fontconfig.
+Once done this will define the following variables:
+
+``Fontconfig_FOUND``
+    True if Fontconfig is available
+``Fontconfig_INCLUDE_DIRS``
+    The include directory to use for the Fontconfig headers
+``Fontconfig_LIBRARIES``
+    The Fontconfig libraries for linking
+``Fontconfig_DEFINITIONS``
+    Compiler switches required for using Fontconfig
+``Fontconfig_VERSION``
+    The version of Fontconfig that has been found
+
+If ``Fontconfig_FOUND`` is TRUE, it will also define the following
+imported target:
+
+``Fontconfig::Fontconfig``
+
+Since 5.57.0.
