## Things You May Have to Modify: ##
## ##
## If the following paths don't point to the place were HDF5 is installed ##
## on your system (i.e., you received a binary distribution or moved the ##
## files from the originally installed directory to another directory) ##
## then modify them accordingly to represent the new paths. ##

## Things You Can Modify to Override HDF5 Library Build Components: ##
## ##
## (Advanced usage - know what you're doing - you're on your own here.) ##
## The four variables below can be used to insert paths and flags in ##
## CPPFLAGS, CFLAGS, LDFLAGS, or LIBS in the h5cc compile line: ##
## $CLINKER $H5BLD_CPPFLAGS $CPPFLAGS $H5BLD_CFLAGS $CFLAGS $LDFLAGS ##
## $LIBS $clibpath $link_objs $link_args $shared_link ##
## ##
## These settings can be overridden by setting HDF5_CFLAGS, ##
## HDF5_CPPFLAGS, HDF5_LDFLAGS, or HDF5_LIBS in the environment. ##
