Misc: Update CMakeLists.txt

 - CMakeLists.txt: add remaining non-debugging compile-time options
   present in Makefile but not here: CONFIG_VSYNC_OPENGL_{FBO,VBO},
   CONFIG_DBUS, and CONFIG_XSYNC.

 - CMakeLists.txt: Use CMakeDependentOption for option dependency.

 - CMakeLists.txt: Remove quotes around library CFLAGS and LDFLAGS to
   allow multiple values.
