Details: That fixes a few bugs, while still having a few missing
things. Don't allow the user to set a shadow build directory, if there
is already a in source build. Detect if a cbp file is already existing
and recent enough, don't rerun cmake then. Ensure that the user runs
cmake with the cbp generator on opening the project. Show the output of
the cmake generator while running. Remove the unecessary cmake step.

Details: Note: I need to refactor the code significantly, i'm more or
less convinced that one build configuration per target is wrong.
We probably want one build configuration per build directory and instead
build all targets that we are interested then in the makestep.
This means we won't have any cmake support for the beta.
