Aah...

Yep, figured that out too ;-)

BTW: I find CMakeLists.txt much easier to read than Makefile.am and I
didn't even read any cmake tutorial yet...

Unfortunately not quite. One problem is that you let flex generate the
kdev-cmg-lexer.cc in the builddir, but add the srcdir/..lexer.cc to the list of
source files. Attached is a patch to fix that.
