Filip,

I believe you should be using --with-hdf5=/usr or perhaps even just
--with-hdf5.  If you use /usr/lib it will look for include files in
/usr/lib/include and libraries in /usr/lib/lib.

It may also be instructive to see what gets inserted in the GDALmake.opt
file at this point:

#
# HDF5 Support.
#
HAVE_HDF5     = no
HDF5_INCLUDE  =

For HDF5 support to work, HAVE_HDF5 needs to be yes, HDF5_INCLUDE needs
to include the appropriate -I directive, and LIBS needs to include the
appropriate library definitions (eg. -L/usr/lib -lhdf5 I imagine).

Best regards,
