I have found the portable way to do this. So cmake provides a command-line tool `touch` (doc <https://cmake.org/cmake/help/v3.7/manual/cmake.1.html#command-line-tool-mode>) which can be used with `execute_process` <https://cmake.org/cmake/help/v3.0/command/execute_process.html>. `execute_process` provides a way to suppress the failure using `ERROR_QUIET` option. Coming back to `touch`, it behaves similar to `file(WRITE ..)` command however, additionally the exit code can be used to check if file was created successfully. This retains the old behaviour while still solving the original problem. I will update the patch.
