Simon Hausmann 174d870635 Add support for picking up vcpkg automatically
If VCPKG_ROOT is defined, let's use it and chainload any previously set
toolchain file. The detection of vcpkg support via the VCPKG_ROOT
environment variable is per vcpkg documentation, the automatic
chainloading is something specific to us.
