2​# FindFontconfig
3​# --------------
4​#
5​# Try to find Fontconfig.
6​# Once done this will define the following variables:
7​#
8​# ``Fontconfig_FOUND``
9​# True if Fontconfig is available
10​# ``Fontconfig_INCLUDE_DIRS``
11​# The include directory to use for the Fontconfig headers
12​# ``Fontconfig_LIBRARIES``
13​# The Fontconfig libraries for linking
14​# ``Fontconfig_DEFINITIONS``
15​# Compiler switches required for using Fontconfig
16​# ``Fontconfig_VERSION``
17​# The version of Fontconfig that has been found
18​#
19​# If ``Fontconfig_FOUND`` is True, it will also define the following
20​# imported target:
21​#
22​# ``Fontconfig::Fontconfig``
