# - 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.

# 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.
