Hi Mikael,
I understand that you want to know the best practice to add the program path for programs intended for compilation.
Instead of dynamically adding paths at runtime, you can set up your paths statically before compilation. You can do this by organizing your code as suggested above and then using the 'mcc' command (MATLAB Compiler Command) with the '-a' option to explicitly add any additional files or folders that are not automatically included due to direct referencing in your code. For example:
mcc -m MyMainScript.m -a /path/to/additional/files
This tells the compiler explicitly about additional files or directories to include in the compilation.
You can also refer to the below mentioned documentation on mcc Comand Line Arguments:
