| <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_PREFIX_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. |
