#2037: HDF5's detect.sh searches for hdf5 in the "usual" directories even when
HDF5_DIR is set

 Priority:  unset   |   Milestone:                     
Component:  Cactus  |     Version:  development version
 Keywords:  HDF5    |  
--------------------+-------------------------------------------------------
 The code in detect.sh passes HDF5_DIR as the "GUESS" (7th) argument of
 find_lib and eventually that argument is *prepended* to the list of
 "usual" directories in bash_utils.sh
 {{{
 local DIRS="$GUESS /usr /usr/local /usr/local/packages /usr/local/apps
 /opt /opt/local $HOME c:/packages"
 }}}

 This seems wrong. If a HDF5_DIR is given then the configure stage should
 fail if HDF5 is not found there. Otherwise the system would unexpectedly
 pick eg a system hdf5 instead of one from a module if the module was
 updated and its path changed.
