I love the idea to set warning flags in platform files but I don't
understand why new files must be created. Is not it possible to add
warning variables to existent platform files in Modules/Platform ?
That would be the end goal. However, if someone wanted it sooner it
could be done inside a project by creating platform files that could be
merged into CVS CMake. My point was that it would be much easier to
merge a platform file based solution than a if,else type solution.
I wonder if it would be possible to add a CMAKE_WARNING_LEVEL variable
(like CMAKE_BUILD_TYPE) which could take values like Warning1,
Warning2, Warning3, Warning4 (or All, Full, No).
So we could define in platform files CMAKE_CXX_FLAGS_WARNING1_INIT,
CMAKE_CXX_FLAGS_WARNING2_INIT... variables (like
CMAKE_CXX_FLAGS_DEBUG_INIT, CMAKE_CXX_FLAGS_RELEASE_INIT).
The final default value for CMAKE_CXX_FLAGS would be
"${CMAKE_CXX_FLAGS_INIT} ${CMAKE_CXX_FLAGS_${CMAKE_BUILD_TYPE}_INIT}
${CMAKE_CXX_FLAGS_${CMAKE_WARNING_LEVEL}_INIT}".
I think it would be a great idea that CMake provide default and
portable warning flags.
I am thinking we could use global properties for this, instead of
variables. Also, no need to use _INIT type stuff as it would not have
to be stored in the cache, and users would never need/want to change them.
If you need any help, I would be very pleased to contribute.
Sounds good.
