Matlab mcc Warning "Adding path ... to Compiler path instance"

Question

I'm compiling my matlab .m functions (and mex files) to run as a standalone program on a Linux server. In the end, I manage to compile all files and even run them, although in the process I do get some warnings:

Warning: Adding path "input_folder1" to Compiler path instance.
Warning: Adding path "input_folder2" to Compiler path instance.
Warning: Adding path "input_folder3" to Compiler path instance.

Basically, my question is what is causing these warnings and how can I avoid them?

And, can I run into trouble if I move this standalone program to a different server?

The mcc line that is causing these warnings is:

mcc -m -d output_folder -I input_folder1 -I input_folder2 -I input_folder3 -a mex_file1.mexa64 -a mex_file2.mexa64 MainScriptFile.m SubFunction1.m SubFunction2.m SubFunction3.m

These warnings are caused by a missing path. If you want to shut them off, you can either disable them using warning off or add the input_folders to the Compiler path before compiling. But since mcc does that anyway (and displays a warning), you can safely ignore them.

Basically, they're just mcc telling you "Couldn't you have done that to start with? Now I'll have to do it myself...".

I can't answer your second question the way it is worded, so I'll have to go with this: You will not run into trouble caused by these warnings or any implications. If you do run into trouble, it's for a different reason.
