Hello,
I am wondering if it is possible to set the target property
'WIN32_EXECUTABLE' on a per-config basis (i.e. you can set link-flags
on a per-config basis using LINK_FLAGS_<Config>). From reading the
documentation this does not seem possible and if you set this property
then all configurations (in Visual Studio) use the same subsystem setting.
I don't know whether or not CMake is able to set a property on a
per-configuration basis. I doubt this is possible (yet), but could be
that I'm wrong here.
But you could simply set the appropriate flags for a console/win32
application yourself, without using this flag at all. The only
differences I could find between a win32 application and a console
application are
- Linker flag: "/SUBSYSTEM:CONSOLE" for console apps and
"/SUBSYSTEM:WINDOWS" for win32 apps
- Preprocessor definition: '_CONSOLE' for console apps
Setting these using LINK_FLAGS_<Config> and COMPILE_DEFINITIONS_<Config>
should do exactly what you want. The only problem I see that could
possibly arise is that you can't depend on the WIN32_EXECUTABLE flag in
your CMake file(s) anymore, to test for it or use it in any other way later.
Another solution that comes to my mind is to always create a win32
application, and then open a console window later by using the win32
function 'AllocConsole' in your code. I never really needed this, but I
know those functions are there to create or attach a console window to a
win32 application. Have a look at the documentation for this function.
