Sometimes, builds fail for errors like

-- PETSc test program - Failed
-- PETSc test program with static linkage - Failed
CMake Error at CMakeLists.txt:252 (message):
  PETSc could not be found, be sure to set PETSC_DIR

This error message is not useful. The real error can be found in palace-build/CMakeFiles/CMakeConfigureLog.yaml. It would be useful to surface this error to the main log so that we can easily diagnose what is going on (e.g., in CI).
