Jed, have you considered adding this to petsc-dev, removing all the
checks for old PETSc releases? Or perhaps better, how about dumping
an autogenerated PETSc.cmake in
$PETSC_DIR/$PETSC_ARCH/conf/PETSc.cmake, or perhaps other name,
defining all the stuff end users need. For example, I'm using the code
below in a codebase I'm working on (note that at the end I'm loading
PETScConfig.cmake), but this is not robust, it does not handle builds
with separate libraries. If PETSc provides all these variables, then I
could simply include (${PETSC_DIR}/${PETSC_ARCH}/conf/PETSc.cmake),
and you can make your FindPETSc.cmake much simpler (at least for the
upcoming version of PETSc)
find_path (PETSC_DIR include/petsc.h HINTS ENV PETSC_DIR DOC "PETSc
Directory")
set (PETSC_ARCH $ENV{PETSC_ARCH})
find_path (PETSC_INCLUDE_DIR petsc.h HINTS "${PETSC_DIR}"
PATH_SUFFIXES include NO_DEFAULT_PATH)
find_path (PETSC_INCLUDE_CONF petscconf.h HINTS "${PETSC_DIR}"
PATH_SUFFIXES "${PETSC_ARCH}/include" NO_DEFAULT_PATH)
mark_as_advanced (PETSC_INCLUDE_DIR PETSC_INCLUDE_CONF)
set (PETSC_INCLUDES ${PETSC_INCLUDE_CONF} ${PETSC_INCLUDE_DIR} CACHE
PATH "PETSc include paths" FORCE)
set (PETSC_DEFINITIONS "-D__INSDIR__=" CACHE STRING "PETSc
preprocesor definitions" FORCE)
find_path (PETSC_LIB_DIR NAMES "" HINTS "${PETSC_DIR}" PATH_SUFFIXES
"${PETSC_ARCH}/lib" NO_DEFAULT_PATH)
find_library (PETSC_LIBRARY NAMES petsc HINTS "${PETSC_LIB_DIR}"
NO_DEFAULT_PATH)
set (PETSC_LIBRARIES ${PETSC_LIBRARY} CACHE FILEPATH "PETSc library" FORCE)
include (${PETSC_DIR}/${PETSC_ARCH}/conf/PETScConfig.cmake)
