[Trilinos-Users] building Trilinos with Intel 7.0

I think at least a partial solution may come from looking at the "classic"
build system which has been used successfully to build Trilinos.  In
particular, you should look at Trilinos/build/makefile.CYGWINICL.MPI.

One thing that the Microsoft and Intel compilers need is a different format
for path specifications, even when compiling in Cygwin.  These compilers
appear to need the DOS path format.

For example, this excerpt from the above mentioned makefile defines the MPI
library location:

LIBMPI = -L "C:\cygwin\usr\local\MPICH\SDK\lib\mpich.lib"

I think the file makefile.CYGWINICL.MPI should have most or all of the
information you need to build with the Intel compilers, but I don't know for
sure since I do not have access to this compiler right now.

Please keep us informed.
