[CMake] Quick Question: add_custom_target( xxx ) add_custom_command( TARGET xxx ... )

[J Decker]

add_custom_target( xxx )
add_custom_command( TARGET xxx
   (PREBUILD? POSTBUILD? PRELINK?)
COMMAND blah )

Why doesn't that work?

Right now I just have a dirty cmake script that does a bunch of macos that
do ...  EXECUTE( cmake copy_if_different )'s and I just want to run those
as a target instead of as 'cmake .'

replacing "EXECUTE( "  with "add_custom_command( TARGET xxx " would be a
really simple conversion....
