- # FindFreetype
- # ------------
- #
- # Locate FreeType library
- #
- # This module defines
- #
- # ::
- #
- # FREETYPE_LIBRARIES, the library to link against
- # FREETYPE_FOUND, if false, do not try to link to FREETYPE
- # FREETYPE_INCLUDE_DIRS, where to find headers.
- # FREETYPE_VERSION_STRING, the version of freetype found (since CMake 2.8.8)
- # This is the concatenation of the paths:
- # FREETYPE_INCLUDE_DIR_ft2build
- # FREETYPE_INCLUDE_DIR_freetype2
- #
- #
- #
- # $FREETYPE_DIR is an environment variable that would correspond to the
- # ./configure --prefix=$FREETYPE_DIR used in building FREETYPE.

- # Try find freetype for our arch in external folder
- #todo: fix location of freetype includes for linux android on cocos prebuilt repo
- #i.e we should not need to include an extra dir of /freetype2
- # Try pkg-config first (because it provided deps info)

- # 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.
