86c80e9 contrib: make check-deps.sh script work with cmake (Ryan Ofsky)

Pull request description:

  Fix check-deps.sh to check for weak symbols so it can detect when an exported template function like is used from another library.

  Also update the script to work with cmake and configure it to run as part of CI.
