Summary

0000096: Warning level in MSVC 7.0

Description

There is variable that can be used for setting warning level (CMAKE_CXX_WARNING_LEVEL).

But default values of CMAKE_CXX_FLAGS contains /W3 (defined in Modules/Platform/Windows-cl.cmake). I think the /W3 option should not be defined in Windows.cl.cmake at all.

Now when I descrease warning level, there are both options (/W2 and /W3) and it prints "overriding /W2 with /W3". So CMAKE_CXX_WARNING_LEVEL is not usable at all.

I need to descrease it because we use exceptions and it prints that exceptions are not supported.

Notes
(0000082) Bill Hoffman (manager) 2003-08-07 09:31	This is a bit tricky to fix the flag CMAKE_CXX_WARNING_LEVEL is only used by the visual studio 7 ide generator. The /W3 is added to the cxx flags by the Platform/Windows-cl.cmake file that is used by nmake and visual stuido 6. What we really need is an abstraction of warnings in CMake. CMAKE_CXX_WARNING_LEVEL (1-10), and this gets mapped onto each compiler differently.
