To build Palomino flight simulator:

UNIX: cmake . && make
FreeBSD: cd /usr/ports/games/palomino; make install
Windows: cmakesetup . then choose Release in Visual Studio.
Problems compiling:
Palomino's cmake files expect OSG to be installed without any build-type suffix.
/usr/local/lib/OpenThreads.so will compile
/usr/local/lib/OpenThreadsd.so won't compile (has Debug suffix)
