Compiling PAL with Bullet Physics 2.75 (Linux)

Install Bullet (Download Link):
cd bullet-2.75/
cmake . -G "Unix Makefiles" -DBUILD_EXTRAS=on -DBUILD_DEMOS=on -DCMAKE_BUILD_TYPE=Debug
make
Pretty simple. The demos will be built to bullet-2.75/demos/ and the Bullet libs are built to bullet-2.75/src/
