# 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``
