+% Zaikun 20240216: The following is a workaround for https://github.com/libprima/prima/issues/161,
+% where MEX fails due to incompatibility between the new linker of Xcode 15 on macOS and Intel oneAPI 2023. 
+% The fix is to replace the linker option "-undefined error" with "-undefined dynamic_lookup".
+% See also https://github.com/libprima/prima/issues/158. 
+% Note that we have to modify `LDFLAGSVER`. Setting `LDFLAGS` or `LINKFLAGS` does not work, although 
+% the latter is suggested at https://www.mathworks.com/help/matlab/ref/mex.html.
