# 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.

# 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.
# Adapted for OpenSceneGraph until the updates here for finding the debug Windows library freetyped are released with CMake
