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.
