> PETSc is already installed and its tests runned but when I try cmake .. for my project it appears that it doesn’t find PETSc. The error message is:

CMake insists on sequestering all the useful information in
CMakeFiles/CMakeError.log and CMakeFiles/CMakeOutput.log.  Can you check
those files for details about the error?  Send the output here if it
doesn't make sense to you.
