| will be ignored. The listed directories do not apply recursively, so any |
| subdirectories to be ignored must also be explicitly listed. |
| <code class="docutils literal notranslate"><span class="pre">CMAKE_SYSTEM_IGNORE_PATH</span></code> does not affect the search <em>prefixes</em> used by these |
| four commands. To ignore individual paths under a search prefix |
| (e.g. <code class="docutils literal notranslate"><span class="pre">bin</span></code>, <code class="docutils literal notranslate"><span class="pre">include</span></code>, <code class="docutils literal notranslate"><span class="pre">lib</span></code>, etc.), each path must be listed in |
| <code class="docutils literal notranslate"><span class="pre">CMAKE_SYSTEM_IGNORE_PATH</span></code> as a full absolute path. <span class="target" id="index-1-variable:CMAKE_SYSTEM_IGNORE_PREFIX_PATH"></span><a class="reference internal" href="CMAKE_SYSTEM_IGNORE_PREFIX_PATH.html#variable:CMAKE_SYSTEM_IGNORE_PREFIX_PATH" title="CMAKE_SYSTEM_IGNORE_PREFIX_PATH"><code class="xref cmake cmake-variable docutils literal notranslate"><span class="pre">CMAKE_SYSTEM_IGNORE_PREFIX_PATH</span></code></a> |

| <p><span class="target" id="index-0-command:find_package"></span><a class="reference internal" href="../command/find_package.html#command:find_package" title="find_package"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">find_package()</span></code></a> is also affected by <code class="docutils literal notranslate"><span class="pre">CMAKE_SYSTEM_IGNORE_PATH</span></code>, but only |
| for <em>Config mode</em> searches. Any <code class="docutils literal notranslate"><span class="pre"><Name>Config.cmake</span></code> or |
| <code class="docutils literal notranslate"><span class="pre"><name>-config.cmake</span></code> file found in one of the specified directories |
| will be ignored. In addition, any search <em>prefix</em> found in <code class="docutils literal notranslate"><span class="pre">CMAKE_SYSTEM_IGNORE_PATH</span></code> |
| will be skipped for backward compatibility reasons, but new code should |
| prefer to use <span class="target" id="index-2-variable:CMAKE_SYSTEM_IGNORE_PREFIX_PATH"></span><a class="reference internal" href="CMAKE_SYSTEM_IGNORE_PREFIX_PATH.html#variable:CMAKE_SYSTEM_IGNORE_PREFIX_PATH" title="CMAKE_SYSTEM_IGNORE_PREFIX_PATH"><code class="xref cmake cmake-variable docutils literal notranslate"><span class="pre">CMAKE_SYSTEM_IGNORE_PREFIX_PATH</span></code></a> to ignore prefixes instead.</p> |
| <p>Ignoring search locations can be useful in cross-compiling environments where |
| some system directories contain incompatible but possibly linkable libraries. |
| For example, on cross-compiled cluster environments, this allows a user to |
| ignore directories containing libraries meant for the front-end machine.</p> |
| <p><code class="docutils literal notranslate"><span class="pre">CMAKE_SYSTEM_IGNORE_PATH</span></code> is populated by CMake as part of its platform |
| and toolchain setup. Its purpose is to ignore locations containing |
| incompatible binaries meant for the host rather than the target platform. |
| The project or end user should not modify this variable, they should use |
| <span class="target" id="index-1-variable:CMAKE_IGNORE_PATH"></span><a class="reference internal" href="CMAKE_IGNORE_PATH.html#variable:CMAKE_IGNORE_PATH" title="CMAKE_IGNORE_PATH"><code class="xref cmake cmake-variable docutils literal notranslate"><span class="pre">CMAKE_IGNORE_PATH</span></code></a> instead.</p> |
