<p>I have a file <code>configuration.ccl</code> like so:</p>
<div class="codehilite"><pre><span></span><span class="o">#</span> <span class="n">Configuration</span> <span class="n">definitions</span> <span class="k">for</span> <span class="n">thorn</span> <span class="n">CMake</span>

<span class="k">VERSION</span> <span class="mi">3</span><span class="p">.</span><span class="mi">15</span><span class="p">.</span><span class="mi">0</span>
<span class="k">OPTIONS</span> <span class="n">CMAKE_DIR</span> <span class="n">CMAKE_INSTALL_DIR</span>
<span>}</span>
</pre></div>
<p>and CST fails with:</p>
<div class="codehilite"><pre><span></span><span>CST error in /data/rhaas/postdoc/gr/cactus/CactusAMReX/arrangements/ExternalLibraries/CMake/configuration.ccl (at 7)</span>

<p>ie the dot “.” is not allowed in version strings. Since these were modeled (somewhat) after Debian version numbers, here’s an example of one of those <code>2:3.6.19-1~bpo70+1+b1</code> and <a data-is-external-link="true" href="https://manpages.debian.org/buster/dpkg-dev/deb-version.7.en.html" rel="nofollow">https://manpages.debian.org/buster/dpkg-dev/deb-version.7.en.html</a> for their definition (upstream version could be any string, really).</p>
