Sure enough, that works also! I have tried it before but did not realize that if
I want the target depend on a file instead of another target, not only do I have
to specify the full path but also the full filename so "libkernel_executable.a"
is necessary instead of "kernel_executable". In the latter case CMake seems to
believe this is another target, tries to build it and fails. Now it makes
perfect sense, thanks for the help, my problem is solved.
