g++ Compiler option for Mac?

[kwunh]

Hello, I am trying to build the library nibrary which has geogram as a dependency.
However, I am installing on to a MacBook Pro (M4 Pro, macOS Sequoia 15.1) and I am getting this error:

make[5]: *** [src/lib/geogram/third_party/CMakeFiles/geogram_third_party.dir/xatlas/xatlas.cpp.o] Error 1
g++: error: unrecognized command-line option '-Qunused-arguments'

So I understand this is an error related to clang but the library I am trying to build does not support clang and instead, I am using homebrew version of g++-14 and gcc-14.

They suggest using a local install of geogram but I am still getting this error. So I suspect I may have to manually switch to g++ for geogram. Is this possible? or is it possible to skip the '-Qunused-arguments' when building my desired library?

Thank you for any help!
