CMAKE_CROSSCOMPILING_EMULATOR — CMake 3.22.2 Documentation

# 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.

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

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.
