FindFreetype
------------
Find the FreeType font renderer includes and library.
Imported Targets
^^^^^^^^^^^^^^^^
.. versionadded:: 3.10
This module defines the following :prop_tgt:`IMPORTED` target:
``Freetype::Freetype``
The Freetype ``freetype`` library, if found
Result Variables
^^^^^^^^^^^^^^^^
This module will set the following variables in your project:
``FREETYPE_FOUND``
true if the Freetype headers and libraries were found
``FREETYPE_INCLUDE_DIRS``
directories containing the Freetype headers. This is the
concatenation of the variables:
``FREETYPE_INCLUDE_DIR_ft2build``
directory holding the main Freetype API configuration header
``FREETYPE_INCLUDE_DIR_freetype2``
directory holding Freetype public headers
``FREETYPE_LIBRARIES``
the library to link against
``FREETYPE_VERSION_STRING``
the version of freetype found
.. versionadded:: 3.7
Debug and Release variants are found separately.
Hints
^^^^^
The user may set the environment variable ``FREETYPE_DIR`` to the root
directory of a Freetype installation.
#]=======================================================================]
# Created by Eric Wing.
# Modifications by Alexander Neundorf.
# This file has been renamed to "FindFreetype.cmake" instead of the correct
# "FindFreeType.cmake" in order to be compatible with the one from KDE4, Alex.
# Ugh, FreeType seems to use some #include trickery which
# makes this harder than it should be. It looks like they
# put ft2build.h in a common/easier-to-find location which
# then contains a #include to a more specific header in a
# more specific location (#include <freetype/config/ftheader.h>).
# Then from there, they need to set a bunch of #define's
# so you can do something like:
# #include FT_FREETYPE_H
# Unfortunately, using CMake's mechanisms like include_directories()
# wants explicit full paths and this trickery doesn't work too well.
# I'm going to attempt to cut out the middleman and hope
# everything still works.
