| ENVIRONMENT_MODIFICATION |
| ------------------------ |
| |
| .. versionadded:: 3.22 |
| |
| Specify environment variables that should be modified for running a test. Note |
| that the operations performed by this property are performed after the |
| :prop_test:`ENVIRONMENT` property is already applied. |
| |
| Set to a :ref:`semicolon-separated list <CMake Language Lists>` of |
| environment variables and values of the form ``MYVAR=OP:VALUE``, |
| where ``MYVAR`` is the case-sensitive name of an environment variable |
| to be modified. Entries are considered in the order specified in the |
| property's value. The ``OP`` may be one of: |
| |
| .. include:: ../include/ENVIRONMENT_MODIFICATION_OPS.rst |
| |
| Unrecognized ``OP`` values will result in the test failing before it is |
| executed. This is so that future operations may be added without changing |
| valid behavior of existing tests. |
| |
| The environment changes from this property do not affect other tests. |
