You set the run time library with the /M* flags in the CMAKE_CXX_FLAGS.

Here is the mapping to the runtime flags:
  if(flags.find("MTd") != flags.npos)
    {
    runtime = 1;
    }
  else if (flags.find("MDd") != flags.npos)
    {
    runtime = 3;
    }
  else if (flags.find("MLd") != flags.npos)
    {
    runtime = 5;
    }
  else if (flags.find("MT") != flags.npos)
    {
    runtime = 0;
    }
  else if (flags.find("MD") != flags.npos)
    {
    runtime = 2;
    }
  else if (flags.find("ML") != flags.npos)
    {
    runtime = 4;
    }

This way the same CMakeLists.txt file should work for visual studio 7 and 6.

I will look at this problem as well.
