But then -g is not used and there will be no debug symbols.
RelWithDebInfo is more what we need.

It is used to have the buildflags set in the environment determine
optimization etc.

CMake apparently uses the absolute path for __FILE__ whereas Autotools
uses the path relative to the Makefile. Hence we get
file-references-package-build-path issues after switching a package to
use the cmake buildsystem.
