vogleditor: Replace hardcoded Qt path with variables generated by cmake's Qt module
sl: Only check the vogltrace library for the architecture that will be used

So that we don't error out even if the other architecture is not built.
sl: Simplify the code that determines which vogltrace library to load (32 or 64)

voglcore: Add pthread as link library

This means any targets that use voglcore will automatically get pthread
include during linking. So we don't need to specify pthread in targets
that don't explicitly use them.
vogleditor: Add link libraries that are needed

Do not hardcode qmake executable, it should be found by the CMake itself.
Find the include directory for libunwind.h.

This allows finding libunwind that has been installed in a non-standard location
just by setting CMAKE_PREFIX_PATH.
Fix some missing libraries.
Make building of OpenGL tests and samples optional.
