| <p>Check if a language can be enabled</p> |
| <p>Usage:</p> |
| <div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">check_language</span><span class="p">(</span><span class="o"><</span><span class="n">lang</span><span class="o">></span><span class="p">)</span> |
| </pre></div> |
| </div> |
| <p>where <lang> is a language that may be passed to enable_language() |
| such as “Fortran”. If CMAKE_<lang>_COMPILER is already defined the |
| check does nothing. Otherwise it tries enabling the language in a |
| test project. The result is cached in CMAKE_<lang>_COMPILER as the |
| compiler that was found, or NOTFOUND if the language cannot be |
| enabled.</p> |
| <p>Example:</p> |
| <div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">check_language</span><span class="p">(</span><span class="n">Fortran</span><span class="p">)</span> |
| <span class="k">if</span><span class="p">(</span><span class="n">CMAKE_Fortran_COMPILER</span><span class="p">)</span> |
| <span class="n">enable_language</span><span class="p">(</span><span class="n">Fortran</span><span class="p">)</span> |
