x86 mac can build pass with following commands:

export CFLAGS="$CFLAGS -I/usr/local/opt/libomp/include"
export CXXFLAGS="$CXXFLAGS -I/usr/local/opt/libomp/include"
export LDFLAGS="$LDFLAGS -Wl,-rpath,/usr/local/opt/libomp/lib -L/usr/local/opt/libomp/lib -lomp"
conan install .. --build=missing -o with_ut=True -s compiler.libcxx=libc++ -s build_type=Release
conan build ..
