Cmake command:

$ cmake -DCMAKE_C_COMPILER=cc -DCMAKE_CXX_COMPILER=CC ..

and then run `make.

An easy fix should be -DSCALAPACK_LIBRARIES=none. The testers won't be able to compare to a reference solution, but should otherwise work.

We don't actually need -lscalapack on Frontier, but I'm not sure the CMake syntax to skip it. Maybe -DSCALAPACK_LIBRARIES= (i.e., defining it as empty) would work.

Thanks @mgates3! I can confirm that -DSCALAPACK_LIBRARIES=none is a workaround. I can now build the tester on Frontier, woohoo!
