variable_requires | |
----------------- | |
Disallowed. See CMake Policy :policy:`CMP0035`. | |
Use the :command:`if` command instead. | |
Assert satisfaction of an option's required variables. | |
:: | |
variable_requires(TEST_VARIABLE RESULT_VARIABLE | |
REQUIRED_VARIABLE1 | |
REQUIRED_VARIABLE2 ...) | |
The first argument (``TEST_VARIABLE``) is the name of the variable to be | |
tested, if that variable is false nothing else is done. If | |
``TEST_VARIABLE`` is true, then the next argument (``RESULT_VARIABLE``) | |
is a variable that is set to true if all the required variables are set. | |
The rest of the arguments are variables that must be true or not set | |
to NOTFOUND to avoid an error. If any are not true, an error is | |
reported. |
