Sure this is fine. You might also want to add in similar COPTFLAGS.

For one the above should be a python list. And then -
configure has trouble with 'spaces' and 'braces' in these paths. Suggest doing:

- create a dir for the required libs - say
mkdir $(HOME)/MKL

copy the required files over here.

and now use:

--with-blas-lapack-lib=[$(HOME)/MKL/mkl_intel_lp64.lib,$(HOME)/MKL/mkl_intel_thread.lib,...]

Also the following might work - but I'm not sure..

--with-blas-lapack-lib="-L$(HOME)/MKL mkl_intel_lp64.lib mkl_intel_thread.lib ..."

If you have issues - send configure.log to petsc-maint

The resultant executable requires MKL dlls to run, specifically fmpich2.dll, libiomp5md.dll, mkl_core.dll, mkl_intel_thread.dll, mpich2mpi.dll. Can I force a static PETSc  build using the MKL libraries? (BTW, using --download-f-blas-lapack produces a statically linked exe.)
