Rolf Eike Beer 1eaf1c9b0f SelectLibraryConfigurations: do not output identical configurations
If the debug and release libraries are the same (which usually means only one
of them was found) do not output the library as "optimized" and "debug", but
just as one plain library. At the end this means that the Find* output of the
avarage (Un*x) user will be much less cluttered.

# select_library_configurations( basename )
#
# This macro takes a library base name as an argument, and will choose good
# values for basename_LIBRARY, basename_LIBRARIES, basename_LIBRARY_DEBUG, and
# basename_LIBRARY_RELEASE depending on what has been found and set. If only
# basename_LIBRARY_RELEASE is defined, basename_LIBRARY, basename_LIBRARY_DEBUG,
# and basename_LIBRARY_RELEASE will be set to the release value. If only
# basename_LIBRARY_DEBUG is defined, then basename_LIBRARY,
# basename_LIBRARY_DEBUG and basename_LIBRARY_RELEASE will take the debug value.
#
# If the generator supports configuration types, then basename_LIBRARY and
# basename_LIBRARIES will be set with debug and optimized flags specifying the
# library to be used for the given configuration. If no build type has been set
# or the generator in use does not support configuration types, then
# basename_LIBRARY and basename_LIBRARIES will take only the release values.
