Our documented standard for find module variable names is to match the case of the find module package name. This was overlooked when the module was added by commit 84e7920b3a (FindFontconfig: Add module to find Fontconfig, 2018-09-27, v3.14.0-rc1~523^2). The module was released with the upper case names in CMake 3.14.0, so fix it to have camel case names in 3.14.1. This is incompatible but anyone using a given release series should be using the latest patch on it and we've made breaking fixups on newly released features like this before.

FindFontconfig
|
|
--------------
|
|
|
|
Find Fontconfig headers and library.
|
|
|
|
Imported Targets
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
``Fontconfig::Fontconfig``
|
|
The Fontconfig library, if found.
|
|
|
|
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
|
|
|
|
