googletest url link is wrong

[tonystarkiss]

the link of googletest in abacus-develop/tests/CMakeLists.txt:
https://github.com.cnpmjs.org/google/googletest.git
should be replaced with https://github.com/google/googletest.git

Thank you for your suggestion. We have fixed this in PR #328 .
cnpmjs.org hosts a mirror to github.com , providing better connection to users located in China. However, it is not a best practice to do so.
For issues, we suggest you raising it on issues page. You can also create a PR fixing this issue by yourself. Again, thanks for your contribution!
