CMAKE_MFC_FLAG

Tell cmake to use MFC for an executable or dll.

This can be set in a CMakeLists.txt file and will enable MFC in the application. It should be set to 1 for the static MFC library, and 2 for the shared MFC library. This is used in Visual Studio project files. The CMakeSetup dialog used MFC and the CMakeLists.txt looks like this:

add_definitions(-D_AFXDLL)
set(CMAKE_MFC_FLAG 2)
add_executable(CMakeSetup WIN32 ${SRCS})
