Any qmake experts out there?

[Lubomir I. Ivanov]

here is my progress in a single patch if someone is interested.

i'm CCing Thiago, because maybe he can help with a qmake issue.

basically i have the same setup that this patch applies in a test project:
- the version_h rule is generated in a .pro (.pri) file
- the rule simply calls a script that may or may not create or update
ssrf-version.h

the problem is that qmake does not generate the rule in the first
place for subsurface (hopefully not a qmake bug).

for my other test project it generates this:
$(DESTDIR_TARGET): ssrf-version.h...

<snip>

ssrf-version.h: FORCE
    @sh ./scripts/write-version ssrf-version.h 4.3 win

the above is not ideal because i think we really want .PHONY but qmake
doesn't really provide us with the option to add to the directive and
what it has instead is QMAKE_EXTRA_TARGETS and PRE_TARGETDEPS.
with FORCE (an empty rule) i have no experience with but it does
generate the ssrf-version.h.tmp file each time 'make' is called, which
is what we want in a way.

any comments are welcome.
