<p>Check if a language can be enabled</p>
<p>Usage:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>check_language(<lang>)
</pre></div>
</div>
<p>where <code class="docutils literal notranslate"><span class="pre"><lang></span></code> is a language that may be passed to <span class="target" id="index-0-command:enable_language"></span><a class="reference internal" href="../command/enable_language.html#command:enable_language" title="enable_language"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">enable_language()</span></code></a>
such as <code class="docutils literal notranslate"><span class="pre">Fortran</span></code>. If <span class="target" id="index-0-variable:CMAKE_<LANG>_COMPILER"></span><a class="reference internal" href="../variable/CMAKE_LANG_COMPILER.html#variable:CMAKE_<LANG>_COMPILER" title="CMAKE_<LANG>_COMPILER"><code class="xref cmake cmake-variable docutils literal notranslate"><span class="pre">CMAKE_<LANG>_COMPILER</span></code></a> is already defined
the check does nothing. Otherwise it tries enabling the language in a
test project. The result is cached in <span class="target" id="index-1-variable:CMAKE_<LANG>_COMPILER"></span><a class="reference internal" href="../variable/CMAKE_LANG_COMPILER.html#variable:CMAKE_<LANG>_COMPILER" title="CMAKE_<LANG>_COMPILER"><code class="xref cmake cmake-variable docutils literal notranslate"><span class="pre">CMAKE_<LANG>_COMPILER</span></code></a>
as the compiler that was found, or <code class="docutils literal notranslate"><span class="pre">NOTFOUND</span></code> if the language cannot be
enabled. For CUDA which can have an explicit host compiler, the cache
<span class="target" id="index-0-variable:CMAKE_CUDA_HOST_COMPILER"></span><a class="reference internal" href="../variable/CMAKE_CUDA_HOST_COMPILER.html#variable:CMAKE_CUDA_HOST_COMPILER" title="CMAKE_CUDA_HOST_COMPILER"><code class="xref cmake cmake-variable docutils literal notranslate"><span class="pre">CMAKE_CUDA_HOST_COMPILER</span></code></a> variable will be set if it was required
for compilation (and cleared if it was not).</p>
<p>Example:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>check_language(Fortran)
if(CMAKE_Fortran_COMPILER)
enable_language(Fortran)
else()
message(STATUS "No Fortran support")
