Hello CMake developpers. We are using execute_process in some of our tests for a Qt based application (ParaView) However, on windows, the GUI does not show up and that caused some problems for rendering.
We have investigated the problem, and it looks like execute_process on windows is based on CreateProcess [1], But CreateProcess cannot interact directly with the user desktop as a GUI would need. It has to do with permissions and system environnement, see the relevant discussions [2], [3] and [4]. So here is my question : Is there a way, using cmake, to start a gui command on windows and have the gui shows up ? If not, is this intended ? Could we have this feature ? Thanks for any hindsight !
