Summary0015688: ADD_CUSTOM_TARGET with Fortran sources creates invalid Unix Makefiles
DescriptionThe add_custom_target allows to specify "sources" for IDE display but if any Fortran source is specified (and Fortran enabled) make fails with

make[2]: *** No rule to make target 'CMakeFiles/copy.dir/requires'. Stop.

The Visual studio generator creates a *.vfproj project in this case where custom commands only work partially (with Intel Fortran Compiler) - instead of a *.vcxproj when no sources are specified.

-> I would expect the build of a custom target to behave identical with or without sources specified.
Steps To ReproduceRun cmake to create Unix Makefiles for attached CMakeLists.txt, run make -> shows specified error
Additional InformationStripped down from a huge project with many targets and a common pre-processing script to combine the fortran inputs for automatic interface check (not just copy like in the example). Works if the "sources" argument is removed from the ADD_CUSTOM_TARGET but for better support by IDEs we like to add this argument.

Adding
  SET_SOURCE_FILES_PROPERTIES(s1.f PROPERTIES LANGUAGE "")
Enables to run the custom command, but the compile does nothing then.

Adding
  SET(CMAKE_Fortran_SOURCE_FILE_EXTENSIONS "FFF")
  SET(CMAKE_Fortran_IGNORE_EXTENSIONS "f")
has no effect at all (and would only help too if it can be reset for and add_executable/add_library)

Identical behaviour of CMake-3.0.2 and CMake-3.3.

Several generators have various special cases when Fortran sources appear in a target. It looks like those need to be made conditional to not apply on custom targets.
