Thanks everyone. After you confirmed that it should work, I had another
close look. I had the template = subdirs set, but qmake gives me
warnings [1] that it cannot find several *.vcxproj files. While
analyzing the logs, I found out that I used an out-of-source build and
qmake expected the *.vcxproj in the source folder instead of the build
folder. If I run the exact same command in the source folder, everything
is perfectly working as you said.

So I assume I just hit a small bug in qmake, that it cannot handle
out-of-source builds properly.

Cheers R.
