BUG: FindSDL now has flag it responds to so it will not find/link against SDLmain. This is required to build libraries instead of applications since they don't have main(). ENH: All modules have a predictable search order, where environmental variables are searched before system paths. This is designed to make automation easier for those that need to automatically build projects without intervention but may be using alternative install locations for isolated testing. ENH: New modules for OpenSceneGraph, Freetype, GDAL, Lua, QuickTime, GIFLIB, Producer, OpenThreads. STYLE: Added documentation explaining peculuar SDL_LIBRARY_TEMP variable in SDL module when library find is incomplete.

# - Locate FreeType library
|
|
# This module defines
|
|
# FREETYPE_LIBRARY, the library to link against
|
|
# FREETYPE_FOUND, if false, do not try to link to FREETYPE
|
|
# FREETYPE_INCLUDE_DIRS, where to find headers.
|
|
# 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.
|
|
# Created by Eric Wing.
|
|
|
|
# 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.
