With './configure; make' of master on macOS 11 on Apple Silicon I get the library detection failure. The quick and easy fix was to amend inc_dirs and lib_dirs in setup.py:

         if MACOS:
+            sysroot = macosx_sdk_root()
+            self.inc_dirs.append(sysroot + '/usr/include')
+            self.lib_dirs.append(sysroot + '/usr/lib')

Interestingly the lzma library is found, but the module fails because it cannot find lzma.h, which does indeed appear to be missing in the SDK.
