The `find_package_handle_standard_args(FOUND_VAR)` is deprecated as of CMake 3.3 and both the `<PackageName>_FOUND` and the upper-cased `<PACKAGE_NAME>_FOUND` are set with or without using this option. Additionally, find modules and docs are also synced with this to make it clearer.

|
|
|
|

|
|
^^^^^^^^^^^^^^^^
|

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
|
|
