How to use "make -j" for Qt Applications?

[youkai]

Hi there!

I want to use all cores for compiling my application. How to do that with MinGW (Windows)?

At first, I got this error:

D:\Projekte\eclipse_workspace\uman\src>make -j 2
mingw32-make: Do not specify -j or --jobs if sh.exe is not available.
mingw32-make: Resetting make for single job mode.

If I use a proper shell (sh.exe), it just compiles - but with only one core.

Any ideas?

as I know mingw doesn't support this feature only gcc under *nix

So what do I have to add to my .pro file to make make run with more than one job,
i.e. how to tell qmake to run make -j? Hmmm?
