I have used CMake in the Gentoo packages pretty much from the start, but
right now I'm experiencing some problems: all is good as long as I have
libsvn support enabled in SG and FG. When I disable it in SG and want to
recompile FG afterwards (also disabled, of course), I get a linking error
for Terrasync:

I don't know if this is caused by the recent cmake changes or rather by the
threads class rewrite...
