How to get current dir using qmake?

[camel]

And, just in case you were interested in a straight answer instead of the "do you really need that what you ask for" answer I gave you above:
Check out

$$_PRO_FILE_PWD_

or

$$OUT_PWD

Not nice, nor documented and I have only checked to see it is in 4.2.2 but this (or rather one of these, depending of use-case) seems to be what you asked for ;-)
