<p>However in this process multiple bugs were introduced (by me). One was reported by <span class="ap-mention" data-atlassian-id="5b59c8ffe288ee2d9b4ba7ba">@Samuel Tootle</span> in <a href="https://bitbucket.org/einsteintoolkit/tickets/issues/2464/linking-errors-with-et_2020_05-with-etk" rel="nofollow" title="Linking errors with ET_2020_05 with ETK built ExternalLibraries" class="ap-connect-link"><s>#2464</s></a>, <span class="ap-mention" data-atlassian-id="557058:1671c5c3-29cc-4e83-9850-a152d33a6235">@Steven R. Brandt</span> just found another one due to using an incorrect variable name in the <code>find_lib</code> call, which went unnoticed on systems where LAPACK / BLAS are found in “standard” locations via pkg-config, which is the majority of systems where it is used it seems.</p>
<p>Fixed in git hash <a data-is-external-link="true" href="https://github.com/einsteintoolkit/ExternalLibraries-BLAS/commits/6e55384a123a37d07896f6e674ff1ac05a16f0a1" rel="nofollow">6e55384</a> "BLAS: fix typo making BLAS_DIR being ignored" of <a data-is-external-link="true" href="https://github.com/einsteintoolkit/ExternalLibraries-BLAS" rel="nofollow">ExternalLibraries-BLAS</a> and git hash
