This is because we should really only allow one project command per CMakeLists.txt file, but since we do not error out, it's difficult to change at this point in time...
--build uses the CMAKE_PROJECT_NAME cache variable to decide what sln file to use, and that corresponds to the first project command. Do you need multiple project commands in your CMakeLists.txt file? What benefit do you get from it? I'd like to understand how people are using multiple project commands, so we can fix this the "right" way.
