Missing INSTALL_ROOT in qmake installation

[atsampson]

Thanks for adding the qmake install rules in version 4.3 - that's made life much simpler for packagers!

The custom install rule for the examples is currently written like this:

examples.extra = find examples -name \'*.xpf\' -exec cp {} $$PREFIX/share/XaoS/examples \;

This doesn't work if you've set INSTALL_ROOT (qmake's equivalent of what most build systems call DESTDIR) to install into a staging dir. Writing it this way generates a correct Makefile rule and fixes the problem for me:

examples.extra = find examples -name \'*.xpf\' -exec cp {} $(INSTALL_ROOT)$$PREFIX/share/XaoS/examples \;

It's not immediately obvious to me from the qmake docs whether you're allowed to refer to its make variables like this, though...

Thanks for this comment. Please do some research if this is widely used by others, that is, if it is at least a de facto standard. If yes, we'll do it similarly.

Pretty surely, note that the other install rules install into INSTALL_ROOT as well.

There's also code missing to create this example directory, I think?

nvm: install_examples even creates it under INSTALL_ROOT, but then copies without INSTALL_ROOT.

Please let me know if that's OK.
