Operator to read environment variables.

Use the syntax $ENV{VAR} to read environment variable VAR.

To test whether an environment variable is defined, use the signature if(DEFINED ENV{<name>}) of the if() command.

See the set() and unset() commands to see how to write or remove environment variables.
