Manual compilation (bullet 3)

You don't need to do this. Just putting it here if you need to compile it

Clone bullet
Compile,

cmake \
    -DLIBRARY_OUTPUT_PATH=<PATH TO THIS REPO>/BulletPhysicsPlugin/Source/ThirdParty/BulletPhysicsEngineLibrary/lib/linux/<RelFolder>\
    -DBUILD_SHARED_LIBS=1 \
    -DINSTALL_LIBS=0 \
    -DINSTALL_EXTRA_LIBS=0 \
    -DCMAKE_BUILD_TYPE=<RelType> \ # Replace build type as required: `Debug`,`RelWithDebugInfo`,`Release`.
    .

make, had to use make -j because, compile was not using all cores for some reason.
