| <p>The system directories that are contained in <code class="docutils literal notranslate"><span class="pre">CMAKE_SYSTEM_PREFIX_PATH</span></code> are |
| locations that typically include installed software. An example being |
| <code class="docutils literal notranslate"><span class="pre">/usr/local</span></code> for UNIX based platforms. In addition to standard platform |
| locations, CMake will also add values to <code class="docutils literal notranslate"><span class="pre">CMAKE_SYSTEM_PREFIX_PATH</span></code> based on |
| environment variables. The environment variables and search locations that |
| CMake uses may evolve over time, as platforms and their conventions also |
| evolve. The following provides an indicative list of environment variables |
| and locations that CMake searches, but they are subject to change:</p> |
