* cmake -E env: Add --modify flagAlex Reinking2022-08-171-0/+1
When `cmake -E env` is given the `--modify` flag, try to parse the following argument as an `ENVIRONMENT_MODIFICATION` operation and apply it to the environment. This generalizes `--unset=`: 1. When implementing `ENVIRONMENT_MODIFICATION` features for other CMake commands, the `MYVAR=OP:VALUE` strings do not need to be translated to OP-specific flags. 2. This provides a natural and consistent extension point to introduce new operations without introducing very many flags. 3. Users need to learn only one syntax to access the same functionality. There is one difference between the behavior here as compared to CTest's interpretation of the `ENVIRONMENT_MODIFICATION` test property. The `MYVAR=reset:` command when run in `cmake -E env` will reset `MYVAR` to whatever its value was when `cmake -E env` launched, rather than try to checkpoint after plain `MYVAR=VALUE` options. This makes `MYVAR=VALUE` and `--modify MYVAR=set:VALUE` semantically equivalent.
