Okay.  We could consider excluding GLOBAL_TARGET targets from the
output.  They never have source files and are nebulously defined.

See the cmGeneratorTarget::GetFullPath.  That is one place that has
been cleaned up to be consistent across generators.

For shared libraries there can be two separate directories on Windows.
The .lib and .dll parts can be in different directories.  I think it
is simpler to enumerate the artifacts with some meta-data about the
type of each one.  The clients can compute from that the directories
or runtime path information that they need.

The information is not associated with cmTarget or cmGeneratorTarget.
Each target may have more than one install rule, so the destinations
are associated with the install rules generated by the install()
command.

See cmInstallTargetGenerator and cmExportInstallFileGenerator for
some of that infrastructure.
