Especially remove "lib64" when the given paths are all Unix ones and "lib" is also explicitely given. In that case CMake will search "lib64" anyway for platforms where it is known to make sense.

# - 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.
