Error: Process finished with exit code 126/Confusion in CLion

Hello, I am a new CLion user and coding for a class in my ECE program.

We are required to clone a repository from github, and I have done so. I cloned it to the default location on my machine, and after many errors later, got the repository able to push/pull and such.

We use somthing called ecegrid to compile things, so I set that up (via ssh) and use it as my compiler. When I try to run my files, I get the following error:

/tmp/tmp.7YUcUO4FxP/Makefile
env: /tmp/tmp.7YUcUO4FxP/Makefile: Permission denied

Process finished with exit code 126

Here is my make file setup:

I am so confused what is happening, and no solutions online have worked. Also, I am not sure how to use the command line in clion as when I click terminal and type things that some solutions have the commands are unrecognized.

Thank you.
