| <p>When a third-party utility’s source is included in the distribution, |
| this command specifies its location and name. The cache entry will |
| not be set unless the <code class="docutils literal"><span class="pre">path_to_source</span></code> and all listed files exist. It |
| is assumed that the source tree of the utility will have been built |
| before it is needed.</p> |
| <p>When cross compiling CMake will print a warning if a <code class="docutils literal"><span class="pre">utility_source()</span></code> |
| command is executed, because in many cases it is used to build an |
| executable which is executed later on. This doesn’t work when cross |
| compiling, since the executable can run only on their target platform. |
| So in this case the cache entry has to be adjusted manually so it |
| points to an executable which is runnable on the build host.</p> |
