Error in gtest when building

[patrickcusack]

I am encountering an error when running "make -j". The test-build-Release.cmake file throws an error.

CMake Error at /Users/me/Documents/working_wdt/wdt-mac/gtest/src/gtest-stamp/gtest-build-Release.cmake:49 (message):

Is gtest necessary and does it require c++11?

[majoros]

you can add "-DBUILD_TESTING=OFF" if your fine forgoing the tests. Otherwise yes you need gtest.

[majoros]

Also if i recall correctly WDT technically only requiters C++11 however Folly, which it depends on, requires C++14.

[ldemailly]

well one could use an older folly that doesn't require c++14 (circa 2017)

I've merged a few PRs that should help with this. Please reopen if this still repros.
