Getting rid of the quotes doesn't change anything.

This isn't helpful without removing all of the benefits of the CMake
standard modules. If I wanted to hard code every library requirement I
would. I'd rather not have to maintain a bunch of separate lists for
each build machine and build OS however. A better example of what I'm
doing, rather than just what triggers this bug, might be the
following:

target_link_libraries( my_project m crypt pthread ) # Needed either way
if( USER_OPTION_X11 )
   include( FindX11 )
   target_link_libraries( my_project ${X11_LIBRARIES} )
endif( USER_OPTION_X11 )
if( USER_OPTION_GTK )
   include( FindPkgConfig )
   pkg_check_modules( GTK REQUIRED gtk+-2.0 )
   target_link_libraries( my_project ${GTK_LIBRARIES} )
endif( USER_OPTION_GTK )

In this case my project needs m, crypt, and pthread no matter what.
Both X11_LIBRARIES and GTK_LIBRARIES also have m and pthread as part
of their required libs. This creates a redundancy and the libraries
for all three are listed multiple times with the gtk libraries being
repeated the most.
