fix compilation error in #69 #92

Problem: As mentioned in this comment of #69, a compilation crashes due to an error of unused variables on Apple silicon (with clang 14 and possibly 13+). This issue has been reported elsewhere. This seems to be caused by breaking behavior in clang 13 which escalates unused variable from a warning in prior versions to an error.

The solution implemented here: I add an additional cflags -Wno-unused-but-set-variable for apple platforms.

Tested on macOS 13.3.1 with Apple clang version 14.0.3 (clang-1403.0.22.14.1)
