try_run: Use CMAKE_CROSSCOMPILING_EMULATOR.
If the CMAKE_CROSSCOMPILING_EMULATOR variable is defined, and
CMAKE_CROSSCOMPILING is TRUE, then use CMAKE_CROSSCOMPILING_EMULATOR to run
the try_run executables. This prevents the need to populate
TryRunResults.cmake when cross compiling.

The ``try_run`` command checks the :variable:`CMAKE_CROSSCOMPILING` variable to detect whether CMake is in cross-compiling mode. If that is the case, it will still try to compile -the executable, but it will not try to run the executable. Instead it +the executable, but it will not try to run the executable unless the +:variable:`CMAKE_CROSSCOMPILING_EMULATOR` variable is set. Instead it will create cache variables which must be filled by the user or by presetting them in some CMake script file to the values the executable would have produced if it had been run on its actual target platform. |
