[CMake] Dependencies

[Petr Kmoch]

Hi Phil.

If your FOO.asm is used as a source file (i.e. it's listed in an
add_executable() or add_library() command), then you can use the source
file property OBJECT_DEPENDS for that:

  add_executable(myexe FOO.asm other.file one.more)

  set_property(SOURCE FOO.asm PROPERTY OBJECT_DEPENDS BAR.mac BAZ.mac) #any
list of dependencies here

As an alternative to set_property(), you can use the weaker, but shorthand
setter set_source_files_properties() (which can set it for multiple files
at once).

If they're somehow processed with a custom command/target (i.e. via
add_custom_command() or add_custom_target() instead of library/executable),
you can use that command's DEPENDS argument.

Petr
