[feature] CONAN_RUNTIME_LIB_DIRS for CMakeDeps

[FeignClaims]

What is your suggestion?

Hi! I'm adding a feature to automatically install conan runtimes in a cmake library aminya/project_options#279. Since the usage of conan is optional, the repo chooses to use cmake-conan. However, CONAN_RUNTIME_LIB_DIRS is set by CMakeToolchain while cmake-conan could only supports CMakeDeps, so I couldn't install runtimes when using cmake-conan.

I would like to have some way to collect CONAN_RUNTIME_LIB_DIRS when only CMakeDeps is specified.

Have you read the CONTRIBUTING guide?

Thanks for your suggestion @FeignClaims

There are some challenges in defining these kind of variables in CMakeDeps generators, because they are very focused on the find_package() and target interfaces. But I am adding this to the next 2.9 for having a look to see if something can be done.

We can probably define this variable in cmake-conan, I think it would make sense to have it.
@memsharded - the implementation would actually be very similar to the solution for conan-io/cmake-conan#669
