I don't have a regular PETSC_DIR but rather an installed version of
PETSc (installed by Dorsal). It looks like it should work anyway since
then PETSC_ARCH can be empty and the following test will still find
petsconf.h in $prefix/include:

if (EXISTS ${PETSC_DIR}/${PETSC_ARCH}/include/petscconf.h)   # > 2.3.3

However, the PETSc test is still failing for me because of problems
with a missing mpi.h:

/usr/bin/c++    -DBOOST_UBLAS_NDEBUG
-DMULTIPASS_TEST_1_petsc_works_minimal
-I/home/logg/scratch/lib/fenics-dev/include   -o
CMakeFiles/cmTryCompileExec.dir/src.cxx.o -c
/home/logg/scratch/src/dolfin-dev/build/CMakeFiles/CMakeTmp/src.cxx

In file included from /home/logg/scratch/src/dolfin-dev/build/CMakeFiles/CMakeTmp/src.cxx:3:
/home/logg/scratch/lib/fenics-dev/include/petsc.h:139:17: error:
mpi.h: Filen eller katalogen finns inte

My mpi.h is in /usr/include/openmpi (symlinked to
/usr/lib/openmpi/include).

I don't see any settings for MPI include path in the PETSc conf
script.
