RelWithDebInfo and MinSizeRel build types not supported with cmake_multi generator

[danimtb]

See comments in https://github.com/bincrafters/community/issues/867

I think the problem should be in this line not taking into account the new build types: https://github.com/conan-io/cmake-conan/blob/c6e5f37b2b0ab52ddc5b9c65e14ad3fd6f6b912f/conan.cmake#L477

However, I tried forcing CMAKE_BUILD_TYPE=RelWithDebInfo and it worked (with single configuration)

Random question: What is the change that broke it in conan / what was the behaviour before 1.16.0? did everything link against the Release libraries when relwithdebinfo was specified?

[danimtb]

For me it has the same behavior (works fine) with both Conan 1.16.1 and Conan 1.15.4 using this command:

$ cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_BUILD_TYPE=MinSizeRel

The issue comes when you want to build with multi config:

$ cmake .. -G "Visual Studio 15 2017 Win64"
...

$ cmake --build . --config Debug
(OK)

$ cmake --build . --config MinSizeRel
(Fails due to conanbuildinfo_minsizerel.cmake not being generated in the first command)

So not sure what is failing in your side. Did you do those steps? Could you post here the commands used?

[munoah]

doesn't cmake just ignore the -DCMAKE_BUILD_TYPE=MinSizeRel when you have visual studio as the generator? I still get a sln file with all 4 build types and I can do cmake --build . --config Debug and then the compiler complains about value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' and stuff like that. I guess thats another problem, the check here https://github.com/conan-io/cmake-conan/blob/f2559b844620a834065d82ad9bc8d488934e2d47/conan.cmake#L468 for a multi_generator is not quite right, maybe it should use this property: get_cmake_property(CONAN_CMAKE_MULTI GENERATOR_IS_MULTI_CONFIG)

But I'm just confused about why using multi config worked before I updated to 1.16.0. I'm also not sure if building all libraries in relwithdebinfo is a good idea since a lot of libraries use standard makefiles or .sln files and these dont have the concept of relwithdebinfo

edit: with conan versions older than 1.16.0 the glm project from the original issue works fine for doing this: cmake .. -G "Visual Studio 15 2017 Win64" cmake --build . --config RelWithDebInfo

@czoido is this problem abandoned or am I missing a solution proposed somewhere else?
