[CMake] Installing a helper application

[Michael Jackson]

Can you use "Find_File()" to get the path to the file. Then use the install(FILES ... ) command to place the file in your app bundle. Not tried any of that but it might work.

On Linux and Win, its sufficient to copy the helper app to the same directory as my app.  On Mac, it needs to be copied into the bundle in the same location as my runtime, in the Contents/Macos/ bundle directory.
