[CMake] WIN32_EXECUTABLE - Config specific settings for visual studio generated project files?

[Jason Eubank]

Thanks Stefan, this worked well.

My exact usage using your recommendations was as follows:

if(WIN32)
    set_target_properties(WindowApplicationExample PROPERTIES
LINK_FLAGS_DEBUG "/SUBSYSTEM:CONSOLE")
    set_target_properties(WindowApplicationExample PROPERTIES RELWITHDEBINFO
"/SUBSYSTEM:CONSOLE")
    set_target_properties(WindowApplicationExample PROPERTIES
LINK_FLAGS_RELEASE "/SUBSYSTEM:WINDOWS")
    set_target_properties(WindowApplicationExample PROPERTIES MINSIZEREL
"/SUBSYSTEM:WINDOWS")
endif(WIN32)

This allows per-config setting of weather or not to use a console in visual
studio, although it does not change the actual Subsytem setting in the
Linker section, it does add it to the Additional Options setting in the
Command Line section, which is then appended to the list of these settings
and produces the same result.

Thanks for the help!

Jason
