@ -28,6 +28,13 @@ quotes, or other characters special in CMake syntax. The options are:
|
|||
directory set to the build directory corresponding to the
|
||||
current source directory.
|
||||
|
||||
The given test command is expected to exit with code ``0`` to pass and
|
||||
non-zero to fail, or vice-versa if the :prop_test:`WILL_FAIL` test
|
||||
property is set. Any output written to stdout or stderr will be
|
||||
captured by :manual:`ctest(1)` but does not affect the pass/fail status
|
||||
unless the :prop_test:`PASS_REGULAR_EXPRESSION` or
|
||||
:prop_test:`FAIL_REGULAR_EXPRESSION` test property is used.
|
||||
|
||||
The ``COMMAND`` and ``WORKING_DIRECTORY`` options may use "generator
|
||||
expressions" with the syntax ``$<...>``. See the
|
||||
:manual:`cmake-generator-expressions(7)` manual for available expressions.
