I don't think I understand your assumption. What do you mean "during
the build"? I think the only way to make sure that your paths are
correct is to do a "fake" install into a temp directory and then do a
For instance, I think we have dist/build/foo/foo.exe (or something)
would get installed in /usr/bin/foo.exe, and dist/doc/foo.html would
be installed in /usr/share/doc/foo/foo.html. So the install paths
aren't correct at build time, only at install time.
