And as Manuel already said, eventually having special subclasses for
some/all target types (testtarget, library target, ...)

The problem is mainly win32 I think (dunno much about OSX, but I know no
other *nix that has the following). There a shared library has _at
least_ two files: .dll and .lib or .dll.a (depending on compiler). The
latter has all the exported symbols for the .dll and is needed to link
against the .dll. Then there's often also an extra library for debug
symbols (IIRC) and eventually a manifest file. If we provide something

We need a way to get these extra files as well, IMHO. If we assume that
we split targetitem into multiple subclasses:

- TestExecutableTargetItem



Then we can just provide a targetUrl() method on those, and for
LibraryTargetItem we can provide something like targetUrl( FileType );
(where FileType would be Library, Import, Debug, Manifest). And of
course defaults to Library.

The problem with just having IBuildSystemManager::url() is that people
who need the import lib or something else are forced to do
someurl.toString().replace(".dll",".lib") and then also check the
compiler as ming actually created .dll.a for import libs.


Time to be aggressive.  Go after a tattooed Virgo.
