CMAKE_MFC_FLAG — CMake 4.1.4 Documentation

# CMAKE_MFC_FLAG

Use the MFC library for an executable or dll.

Enables the use of the Microsoft Foundation Classes (MFC). 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.

Contents of `CMAKE_MFC_FLAG` may use `generator expressions`.

## Examples

Usage example:

    set(CMAKE_MFC_FLAG 2)

    add_executable(CMakeSetup WIN32 ${SRCS})

    # Visual Studio generators add this flag automatically based on the
    # CMAKE_MFC_FLAG value, but generators matching "Make" require it:
    target_compile_definitions(CMakeSetup PRIVATE _AFXDLL)
