Forcing Conan build type to match CMake one

[mous16]

Invoking Conan with -s build_type= parameter matching active CMake build type, or all the active ones if in multi-config scenario.

This allows CMake to correctly build targets and link to correct Conan-insatlled dependencies.

Is this desirable? I usually prefer to build the dependencies as Release unless there is an issue I need to debug in them.

I thought the same, until I stumbled across MSVC, which builds iterators with some additional introspection features when in Debug mode, making them not binary compatible with Release mode builded ones. Here more infos abaout.
So, tring to link a debug executable with a non debug library results in errors.

Moreover, using Ninja in multi-config mode, together with Conan with cmake_find_package_multi generator, causes CMake to generate only <MODULE>-release.cmake file, making it impossible to build in Debug mode (nor in RelWithDebInfo or MinSizeRel).

I'll try to upload a minimal example as soon as possible.

Thanks for the clarification!

Feel free to add the example as a test.
