Thank you for feedback Michael. I take care about maintaing a bunch of
common cmake scripts for group of developers.
The workflow is a little bit complicated to describe it in short. I
just need to know
the compilation status form other processes that call: make all and
make package.
Therefore I think simply file flag is the best choice. I don't wont to
make it in wrapper
for make and I'm looking for solution in cmake.

The implementation of this ticket
http://www.cmake.org/Bug/view.php?id=8438#c26520 will help me.
However this is 2,5 years old ticket so I'm looking for some time
being solution.

Thanks, T. Majchrowski.
