No, it doesn't get written to the Makefile. This really is a call to stdout.
No WriteLocalMakefile or or similar involved.
But at least this opened my eyes :)
I simply grepped for it in the cmake-sources after a grep on the builddir
did not result in any output - but did not look at the filename. But I got
that "Scanning ..." message when I (tried to) build with ninja :oops:
Really can't tell you what I actually did - was in a hurry...
But now everything goes fine! Changing the Generator in the ebuild was easier
than I guessed - just set a variable. Build time dopped by 30 minutes!!
Great!
And thx alot for your help.
