<p>Comment (by Roland Haas):</p>
<p>Ideally the library would become an ExternalLibrary (same as say LORENE <a data-is-external-link="true" href="https://github.com/einsteinToolkit/externalLibraries-lorene" rel="nofollow">https://github.com/einsteinToolkit/externalLibraries-lorene</a>) and the reader thorn would REQUIRE it (like Meudon_Bin_NS <a data-is-external-link="true" href="https://bitbucket.org/einsteintoolkit/einsteininitialdata/src/master/Meudon_Bin_NS/" rel="nofollow">https://bitbucket.org/einsteintoolkit/einsteininitialdata/src/master/Meudon_Bin_NS/</a> in file configuration.ccl).</p>
<p>This has the advantage that multiple different ID readers can use the same ExternalLibrarry eg for BBH or BNS or BHNS initial data. Those should not be all handled by a single thorn since eg the BNS or BHNS reader will need to provide data in thorn HydroBase which would not be active for a pure vacuum run.</p>
<p>If the library cannot be incorporated as an ExternalLibrary (eg b/c it requires use of C++ features not allowed in C++11 or Fortran newer than Fortran 2008) then you could have the ID thorns take <code>FOO_DIR</code> etc option list variables the way an ExternalLibrary thorn would do. However this would mean that a user who would like to compile in multiple different ID thorns all using Elliptica’s library would have to, potentially, set multiple option list variables with identical values.</p>
<p>On the technical level, you can tell the build system which library to link against and the path to find is using configuration.ccl by adding a (<a data-is-external-link="true" href="http://einsteintoolkit.org/usersguide/UsersGuide.html#x1-53000C1.2.3" rel="nofollow">http://einsteintoolkit.org/usersguide/UsersGuide.html#x1-53000C1.2.3</a>) block</p>
