[CMake] VS2010: /subsystem:console only in debug build

[Hauke Heibel]

Hi Andreas,

as far as I know, your only chance to achieve this is by modifying your
source code by adding

#ifndef NDEBUG
#pragma comment(linker, "/SUBSYSTEM:CONSOLE")
#endif

Using add_executable(... win32 ...) is correct because the pragma statement
will override the behaviour in debug mode (in my example in all but release
builds)

I hope this helps.

Regards,
Hauke
