Note that MAP_IMPORTED_CONFIG_<CONFIG> should not be set by package
configuration files.  It should only be set in the CMakeLists.txt files
of the project *loading* them.  Only the application knows its own list
of configurations.  The documentation of the package should list the
valid configurations to which one may map.

It shouldn't be necessary to create the non-config one.  If only
IMPORTED_LOCATION_DEBUG and IMPORTED_LOCATION_RELEASE are set and not
IMPORTED_LOCATION then the default behavior will still choose one of
the available configurations.  Just be sure to list all the available
configurations in IMPORTED_CONFIGURATIONS.
