audacity-2.4.2-r3.ebuild has something for this already:
``append-cxxflags -std=gnu++14''
Check out flag-o-matic.eclass. Note that the build system could still
be overriding it, so if that fails, I'd check the compilation commands
for -std=... parameters, as well as CXX_STANDARD_LEVEL, or whatever
cmake calls it.
Hope that helps, have a great day.
