# CMAKE_CROSSCOMPILING_EMULATOR

New in version 3.3.

This variable is only used when `CMAKE_CROSSCOMPILING` is on. It should point to a command on the host system that can run executable built for the target system.

New in version 3.15: If this variable contains a semicolon-separated list, then the first value is the command and remaining values are its arguments.

New in version 3.28: This variable can be initialized via an `CMAKE_CROSSCOMPILING_EMULATOR` environment variable.

The command will be used to run `try_run()` generated executables, which avoids manual population of the `TryRunResults.cmake` file.

It is also used as the default value for the `CROSSCOMPILING_EMULATOR` target property of executables.
