Hi,
You need a C++14 compliant compiler. For the reasons I can't fully understand you sometimes must pass CXX flags manually, as cmake setting that I think should work doesn't
Have a look at
https://github.com/mlukaszek/evdipp/...er/.travis.yml - this is the configuration for Travis CI. I was forced to run cmake with -DCMAKE_CXX_FLAGS="-std=c++14" as you'll see.
Cheers,
Michal
