Tetgen1.5.mexmaca64 file is missing

Hi,
I am seeking help to generate the head model for my project. While performing FME mesh generation, the tool is looking for tengen1.5.mexmaca64 binary file. I understand the existing tool does not have the Apple silicon-supported mex files. I need suggestions to solve this issue. Do I have any chance to get the tengen1.5.c file to generate the system-compatible mex file ?

Regards
Masuma

It seems to be the same issue as in the other post:
