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.
