[osg-users] freetype build support on Windows

[Robert Osfield]

Hi Stuart,

It sounds like the version of Freestyle is broken or it requires a tweak to
configuration. Have you approached the freetype community about these
issues.

The debug vs release issue is something that would be worth raising with
the cake community as it sounds like a revision to their Findfreetype.cmake.
