When you open a CMake project, you need to configure a build directory. 
I think it should go without saying that this directory is going to be 
created.

I just discovered something else. If you switch from Ninja to Unix 
Makefiles, then even if the checkbox is disabled, the directory is still 
created and there's no error message anymore. So the whole thing seems 
to be inconsistent, too :-)
