cmake: Wrap vcpkg code in a function.
Wrap the main body of code in Set-Toolchain-vcpkg.cmake in the vcpkg_set_toolchain() function to not pollute the global variable namespace with helper variables. VCPKG_ROOT and toolchain variables are set in the cache. Signed-off-by: Rafael Kitover <rkitover@gmail.com>
