Hi Jed,<div><br></div><div>Apparently it's failing to run the test script (it says PETSC_EXECUTABLE_RUNS was not set). If I'm correct, the output of the failed test script should be in CMakeFiles/CMakeError.log . Looking at this, it gives me the following:</div>

<div><br></div><div>I realize it's probably bad practice, but I also thought I would try to disable this flag by forcing PETSC_EXECUTABLE_RUNS to "YES", but it doesn't seem to work. I tried commenting out if (${${run}}) and the corresponding endif, as well as moving it outside the macro. I feel rather silly about this, but I just cannot get it to work.</div>

Hello,<div><br></div><div>I'm working on a large numerical software project whose framework has largely been developed already. We're using CMake to generate makefiles. I'm also using SLEPc (for full disclosure). The examples given by PETSc and SLEPc documentation require me to include makefiles, but I don't know of any straightforward way to command CMake to do this for me.</div>
<div><br></div><div>I have looked at the FAQ's link for the CMake question: <a href="https://github.com/jedbrown/dohp" target="_blank">https://github.com/jedbrown/dohp</a> But this seems very old, and in any case it doesn't exactly work. </div>

<div>I'm not an expert on CMake, so I couldn't say what was the causing the problem, but in the end it told me it could not find the PETSc libraries. It seemed to be rather complicated-- I know PETSc will be where I need it, so I don't need all the verification that it's there and everything works. I thought, with the benefit of more intimate knowledge of how PETSc runs, that someone could show a much simpler way (it seems to me that this ought to be the case).</div>
</blockquote><div><br></div></div><div>The problem is that there are lots of ways that things can "not work", so its important for the FindPETSc.cmake script to really try. Also, CMake insists on taking parameters in a different way (e.g. converting command-line flags to full paths).</div>
