I have no way to see if this works because I do not have an M3, but it
looks like run_cmake generates the config.h file in the build directory
(same as where run_cmake is found) and in that file you see:
CC=/usr/bin/clang
CFLAGS= -Wall -Wno-unused-function
CNOOPTFLAGS=
COPTFLAGS=-O3 -mtune=native
CXX=/usr/bin/clang++
CXXFLAGS= -Wall -Wno-unused-function -stdlib=libc++
CXXNOOPTFLAGS=
CXXOPTFLAGS=-O3 -mtune=native
I would change native to m2 maybe ?
do this after run_cmake and before make_install
Please let me know if this works.
