OpenSceneGraph/CMakeModules/FindFreeType.cmake
Robert Osfield f5ec89e049 From Eric Wing, "Attached are a few Find modules with updates. Among other things, they
contain better support for environmental variables to pre-empt the
autodection default search path order which is very helpful for people
who do automated builds. (I recommend that the remaining modules
consider adding the same system to make things consistent and easier
for those people that want to do the automated builds.)

The CMAKE_PREFIX_PATH has also been added to help people. I don't
recommend adding this to the other modules because it looks like CMake
agreed with my idea and will be adding the support in 2.6. So when
that ships, people will get it for free. (In the meantime, my modules
that do have it, it can be used.)

Finally, I've submitted all of these modules to official CMake plus
more so they will be in the next version of CMake. It looks like I may
need to sort some compatibility issues out with the KDE people who
seem to have conflicting modules, but this is unrelated to the updates
submitted here as OSG already has these conflicts. I figured I would
just sync OSG up with my current/best versions.

Also of note, I added the large batch of Findosg*.cmake modules to
CMake so people building against OpenSceneGraph can use these without
writing their own. I wasn't sure if I should submit them here or not
since they are for building against OSG and not for building OSG
itself. So they are not included.

# - 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.
