Eos: Ran into issue when building with MacOS10.12. Any ideas?

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
EOS_LIBBSONCXX
linked by target "db_plugin" in directory /Users/hyperbola/Documents/eos/plugins/db_plugin
EOS_LIBMONGOCXX
linked by target "db_plugin" in directory /Users/hyperbola/Documents/eos/plugins/db_plugin

I've ported recent changes in plugins/db_plugin/CMakeLists.txt (which is currently plugins/mongo_db_plugin/CMakeLists.txt) from master branch to fix this.

@blackbeam Thanks a lot! I will follow your way and try it.

@blackbeam Where did you merge these changes to? I'm having this same issue when building DAWN-2018-02-14 on Ubuntu 16.04. Thanks!

[blackbeam]

Into my local copy of the eos source code (file plugins/db_plugin/CMakeLists.txt as stated in the diff posted above).

@blackbeam Do I need to build again after making changes to CMakeLists.txt?

[blackbeam]

@SonikaManandhar. As far as I can see build of DAWN-2018-02-14 won't start without it if your mongo driver version >= 3.2 (see c166966). So if you experienced this error, then you need to apply this changes and restart build.

[SonikaManandhar]

@blackbeam Thank you for the response.
I was able to make it work after rebuilding and making few more changes in the file paths.
