I am trying to create and deploy a custom "jetton" via contract. I have found the TONCLI for the job. I followed a guide while setting it up. "toncli" command works fine. "toncli start jetton_minter" works fine. But when I try "toncli build", I get the error

"""
cannot open source file params.func
#include "params.func";
^
"""

The file is in the folder which is stated by the "project.yaml" file. What am I missing?
