Please provide way to override CMAKE_MSVC_RUNTIME_LIBRARY in triplet file

[ccpjosephf]

We never link against the debug version of CRT

Even when we build debug configurations, we always want to pass /MD or /MT, never /MDd or /MTd

However there doesn't seem to be a way of overriding this behavior for building dependencies in VCPKG without setting VCPKG_CHAINLOAD_TOOLCHAIN_FILE in the triplet and setting CMAKE_MSVC_RUNTIME_LIBRARY from there. Setting VCPKG_CHAINLOAD_TOOLCHAIN_FILE causes all compiler detection to be dropped, which is also undesirable.

If there is already a simple way to do what I have described, could someone point this out to me? Is there is a way to set VCPKG_CHAINLOAD_TOOLCHAIN_FILE and keep the compiler detection?

Otherwise this is a feature request
