CPack NuGet configuration misses "repository" tag

There is no way to specify repository tag with CPACK (Variables to CPack NuGet generator) which deviates from current nuspec specification.

Add/support following or similar tags

set(CPACK_NUGET_PACKAGE_REPOSITORY_TYPE "git")

set(CPACK_NUGET_PACKAGE_REPOSITORY_URL "https://github.com/this_repository")

set(CPACK_NUGET_PACKAGE_REPOSITORY_BRANCH "<your_branch_here>")  

set(CPACK_NUGET_PACKAGE_REPOSITORY_COMMIT "<your_hash_here>")  

which should translate into

<repository type="git" url="https://github.com/this_repository" branch="<your_branch_here>" commit="<your_hash_here>" />
