<p>The first argument is the file name, the rest of the arguments are
messages to write. If the argument <code class="docutils literal notranslate"><span class="pre">APPEND</span></code> is specified, then the
message will be appended.</p>
<p>NOTE 1: <span class="target" id="index-1-command:file"></span><a class="reference internal" href="file.html#command:file" title="file"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">file(WRITE)</span></code></a> and <span class="target" id="index-2-command:file"></span><a class="reference internal" href="file.html#command:file" title="file"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">file(APPEND)</span></code></a> do exactly
the same as this one but add some more functionality.</p>
<p>NOTE 2: When using <code class="docutils literal notranslate"><span class="pre">write_file</span></code> the produced file cannot be used as an
input to CMake (CONFIGURE_FILE, source file ...) because it will lead
to an infinite loop.
