- utility_source
- --------------
- Disallowed. See CMake Policy :policy:`CMP0034`.
- Specify the source tree of a third-party utility.
- ::
- utility_source(cache_entry executable_name
- path_to_source [file1 file2 ...])
- 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 ``path_to_source`` and all listed files exist. It
- is assumed that the source tree of the utility will have been built
- before it is needed.
- When cross compiling CMake will print a warning if a ``utility_source()``
- 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.
