Hi,

I'm trying to figure out with cmake whether netcdf was built with hdf5 mpi
parallel IO support, I can compile a test program but I cannot expect it to
run as many of the systems I run on use cross compiling.

Variables like NC_MPIIO and NC_COLLECTIVE  appear to be defined even if
this mode is not available as is the function nc_var_par_access.

On some systems I can try linking without mpi and look for the link errors,
but the compiler wrappers on other systems (eg cray) don't make it easy to
compile without mpi.

Any suggestions?
