[SCons] Build with Solid as default when enabling the gameengine in the build process [SCons] Build solid and qhull from the extern directory and link statically against them That was about it. There are a few things that needs double checking: * Makefiles * Projectfiles * All the other systems than Linux and Windows on which the build (with scons) has been successfully tested.
