The execute_process commands seems to work fine for this.

Since 2.8.12 was released CMake 'master' in Git replaced the underlying implementation of exec_program with the same infrastructure used by execute_process. Local testing says this issue was fixed by that.

Please try with CMake 'master' built from source, or try a nightly 'next' binary from:
