SelectLibraryConfigurations: Use -NOTFOUND instead of copying the vars
If one of the libraries (_DEBUG or _RELEASE) is not set, the value is set to the value of the other one. FindQt4, from which the macro is extracted, sets the values to XXX_LIBRARY_{DEBUG,RELEASE}-NOTFOUND instead. In both cases the XXX_LIBRARY is correct, but using NOTFOUND makes it easier to understand which one is missing. Update Tests/CMakeOnly/SelectLibraryConfigurations with the new logic.

-# basename_LIBRARY_DEBUG is defined, then basename_LIBRARY,

+# basename_LIBRARY_RELEASE is defined, basename_LIBRARY will be set to the

#
# If the generator supports configuration types, then basename_LIBRARY and
