[CMake] Installing a helper application

[Ryan Pavlik]

You'll need something closer to this:


add_executable(myapp MACOSX_BUNDLE [...])

find_file(helperpath [...])
if(NOT helperpath)
message(FATAL_ERROR "Need helper app!")
endif()

install(TARGETS myapp
   BUNDLE DESTINATION .
   RUNTIME DESTINATION bin
)

if(APPLE)
install(PROGRAMS ${helperpath}
   DESTINATION ./myapp.app/Contents/MacOS
)
else()
install(PROGRAMS ${helperpath}
   DESTINATION bin
)
endif()
