generally looks fine and Aleix and me both wanted this change.

Review:

1) QWidget* window(QApplication:.activeWindow()) - not required, the 
activewindow is a QWidget.

2) Cmake might still have a problem with this, afaik it reloads the project as 
soon as a CMakeLists.txt is removed, hence the folders might be invalid 
afterwards. Aleix? Maybe we need to pass one big list of items instead of 
differentiating between files and folders?

3) the typedefs in ibuildsystemmanager seem to be unused?

4) Aleix will have to review the CMake part

So, I'm all in favor of pushing this. to fix (1) you should make sure you don't 
pass something like this to the manager:

foo/
foo/bar/
foo/bar/asdf.txt

But instead only:

foo/

Bye
