Properly utilize user CXX and CXXFLAGS

So, it does actually have something for setting the compiler it's just in a GPP variable. I adjusted the build system to use CXX instead, and also made sure CXX compiles were actually using user CFLAGS. Confirmed compilation with both clang and gcc

Thank you for your support. I've pushed your patch.

[Comment 3 Thomas Deutschmann (RETIRED) 2016-11-21 13:00:39 UTC]

The make system is still calling g++ directly, see the tracker.

I am suggesting the following changes:

In addition I see that ntopng links to libzmq.so.5, libjson-c.so.2 and libhiredis.so.0.13 on my system. So it looks like you didn't catch all the dependencies.
