Fix to allow ninja to use make for generators (#123)

[yashi]

This is a backport of upstream commit ade88c5. This allows ROS Humble LTS to be compiled with Ninja.

Without this, colcon build with an environment variable CMAKE_GENERATOR=Ninja for packages depending on python_qt_binding fails with the following error.
