[CMake] Mfc flag

[Denis Scherbakov]

Elizabeta,

In your code snippet everything is ok. CMAKE_MFC_FLAG is 2 after it is set. No sooner no later. If you give complete example, which does not work, then you'll get an answer.

Did you mean the following?

ADD_SUBDIRECTORY(ProjectA) # MFC_VAR not defined
SET (MFC_VAR 2)
ADD_SUBDIRECTORY(ProjectB) # MFC_VAR == 2

I would advise against declaring variables with CMAKE_ prefix, since they can interfece with internal CMake variables.
