That almost works except that petsc.h doesn't include all
definitions/declarations.  I have a function which cannot be compiled by
just adding petsc.h with errors like:
error: identifier "CUSPARRAY" is undefined
error: identifier "Mat_SeqAIJ" is undefined
error: identifier "Mat_SeqAIJCUSP" is undefined
ect.
But it can be compiled if I add the following in addition to petsc.h

PETSC_CUDA_EXTERN_C_BEGIN
#include "../src/mat/impls/aij/seq/aij.h"          /*I "petscmat.h" I*/
#include "petscbt.h"
#include "../src/vec/vec/impls/dvecimpl.h"
#include "private/vecimpl.h"
PETSC_CUDA_EXTERN_C_END
#undef VecType
#include "../src/mat/impls/aij/seq/seqcusp/cuspmatimpl.h"

What's the minimal set of headers I can add to petsc.h such that I can call
alll petsc functions and use all petsc type?
Thanks.
