+CMAKE_CROSSCOMPILING_EMULATOR
+-----------------------------
+
+This variable is only used when :variable:`CMAKE_CROSSCOMPILING` is on. It
+should point to a command on the host system that can run executable built
+for the target system.
+
+The command will be used to run :command:`try_run` generated executables,
+which avoids manual population of the TryRunResults.cmake file.
+
+It is also used as the default value for the
+:prop_tgt:`CROSSCOMPILING_EMULATOR` target property of executables.
