SelectLibraryConfigurations
---------------------------



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 will be set to the release value, and
basename_LIBRARY_DEBUG will be set to basename_LIBRARY_DEBUG-NOTFOUND.
If only basename_LIBRARY_DEBUG is defined, then basename_LIBRARY will
take the debug value, and basename_LIBRARY_RELEASE will be set to
basename_LIBRARY_RELEASE-NOTFOUND.

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 value, or the debug value if the release one is
not set.
