No rule to make target 'foodie_adt_integrand.f90'

Hey, I wanted to say first this project looks super cool and I hope I can get it to work!

I just cloned the repository to my local machine through:
`git clone https://github.com/Fortran-FOSS-Programmers/FOODIE`

and then after reading the readme here, I tried to:
`make foodie`

but received the following output and error:
```
Wills-Freaking-MacBook-Pro:FOODIE willsharpless$ make foodie
Building foodie
/Library/Developer/CommandLineTools/usr/bin/make FC=bgxlf2008_r FCFLAGS="-qsuffix=cpp=f90" --directory=src/lib
/Library/Developer/CommandLineTools/usr/bin/make foodie
make[2]: *** No rule to make target `foodie_adt_integrand.f90', needed by `foodie_adt_integrand.o'. Stop.
make[1]: *** [all] Error 2
make: *** [foodie] Error 2
```
I tried running `make all` but also got the exact same output. Did I miss something in the clone?

Note, I have a Mac with macOS Catalina 10.15.7.
