[osg-users] freetype build support on Windows

[Robert Osfield]

Hi Stuart,

I have now checked in my changes to build the OSG using CMake's
FindFreetype.cmake rather than the OSG's native one, I deleted the
later as well as change the src/osgPlugins/freetype/CmakeListst.txt.
I have tested this under Kubuntu 16.04 so far.

After checking the changes in I am now starting to think that using
the standard Windows 3rd party depdencies package and the associated
Find3rdPartyDependencies.cmake might not set up the variables in the
same way as CMake's FindFreetype.cmake so could lead to problems.  In
particular I don't think the FREETYPE_LIBRARIES var usage that I've
introduced will work with the Find3rdPartyDependencies.cmake that will
be just setting the FREETYPE_LIBRARY var.

I think Find3rdPartyDependencies.cmake should be creating a
FREETYPE_LIBRARIES var as well, but am not a CMake guru so will need
to look up the rules for doing this.

Robert.

In the attached FindFreetype.cmake I just hacked it to work with the new layout but that obviously won't work for the old layout. Does some CMake guru know the right way to do this? Would it work to just drop the OSG custom FindFreetype.cmake and use the CMake one (which seems to have both include/freetype2 and include supported in the latest CMake)?
