Looking at hdf5. Seems as though the

 ... hdf5-hdf5_1.14.6/release_docs/RELEASE.txt :

    Configuration
    -------------
    - When using a system installed zlib library, the shared library is expected to
      be found in the system library path with the default HDF5_MODULE_MODE_ZLIB
      setting ON.

      Setting the HDF5_MODULE_MODE_ZLIB option to OFF, the system installed zlib,
      or an alternate installed zlib library, is expected to have a correct
      zlib-config.cmake file.

      Fixes #5155 

    - Use pre-installed libaec compression library

      The CMake logic for finding the libaec compression library has been
      modified for a system-installed version of the library. Two options
      must be set;
          HDF5_ALLOW_EXTERNAL_SUPPORT:STRING=NO
          <LIB_PKG_NAME>_USE_EXTERNAL:BOOL=OFF
      where <LIB_PKG_NAME> is one of ZLIB, ZLIBNG, SZIP, PLUGIN.
      Note that HDF5_ALLOW_EXTERNAL_SUPPORT:STRING=NO disables building all
      plugins and external libraries in-line with the HDF5 library.
    
      In addition, the <LIB_PKG_NAME>_ROOT environment variables must be set,
      where <LIB_PKG_NAME> is one of ZLIB, ZLIBNG, SZIP, libaec, PLUGIN.
      Note that libaec is the expected name for using the libaec library in
      place of original szip.
      
      See INSTALL_CMake.txt for more detailed information.

    - Removed the module search find_package for szip library

      There is not an szip module file to use, so the find_package only uses
      find_package in config mode. The remaining choices are to either build szip
      with libaec inline, or find a system installed szip library built with CMake.

To build HDF5 with the SZIP and ZLIB external libraries you will need to:

devel/zlib exists and the hdf5 Makefile includes:
.include "../../devel/zlib/buildlink3.mk"
but there is no devel/szip

So what would be a good way to have hdf5 include szip?
