FindFontconfig
--------------
.. versionadded:: 3.14
Finds Fontconfig, a library for font configuration and customization.
Imported Targets
^^^^^^^^^^^^^^^^
This module provides the following :ref:`Imported Targets`:
``Fontconfig::Fontconfig``
Target encapsulating the Fontconfig usage requirements, available if
Fontconfig is found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``Fontconfig_FOUND``
Boolean indicating whether the (requested version of) Fontconfig is found.
``Fontconfig_VERSION``
The version of Fontconfig found.
``Fontconfig_LIBRARIES``
The libraries to link against to use Fontconfig.
``Fontconfig_INCLUDE_DIRS``
The include directories containing headers needed to use Fontconfig.
``Fontconfig_COMPILE_OPTIONS``
Compiler options needed to use Fontconfig. These should be passed to
:command:`target_compile_options` when not using the
``Fontconfig::Fontconfig`` imported target.
Examples
^^^^^^^^
Finding Fontconfig and linking it to a project target:
.. code-block:: cmake
find_package(Fontconfig)
target_link_libraries(project_target PRIVATE Fontconfig::Fontconfig)
