[petsc-dev] PETSc 3.5.3 and CMake

[Garth N. Wells]

You can find a maintained FindPETSc.cmake file at

    https://bitbucket.org/fenics-project/dolfin/src/2925b1aaa49993fa294e52ae335b4762c1298598/cmake/modules/FindPETSc.cmake?at=master


It was originally based (loosely) on FindPETSc.cmake file by Jed.
