Not rely on (LL_)USESYSTEMLIBS macro & CMake setting

but the fact that we keep on using as many system libraries as we
can (and only resort to other sources in certain cases), hasn't
changed, of course.
Also stop having to set USE_AUTOBUILD_3P to OFF.
Lines are reindented, and when a system library can be found for
a dependency, then that should be the way. If later we find out
that using some other way is better, than stick to that. So, one
option at a time, whichever is best for the situation.
GLEXT hasn't been used, and in order to be not having to hack its
.cmake file, we bypass it and refer to GLH (which is still used)
right away in LLWindow.
CMake commands that need to be bypassed, if it's a one-liner then
it's just commented out, but if it's multiple lines, then scope
them with if (FALSE) to minimise difference.
