I'm seeing an extremely strange behavior with add_custom_command/add_custom_target, and I'm not sure what's causing it.
Background: I'm trying to copy large numbers of files in batch lots during the make process, with a custom target that depends on a list of files and runs a single copy process (cmake -P file.cmake where file.cmake contains the list and the FILE(COPY command) to copy them all in one gulp if any of them changes. This works, but some of the copy processes do not terminate (i.e. multiple calls to make result in the copy happening each time, even though the files have already been copied.) The termination failures appear to be consistent, but for the life of me I can't figure out what is causing them. I have a list: SET(tclscripts_TCLSCRIPTS ami.tcl ampi.tcl cad_clrpick.tcl cad_dialog.tcl chkexterns.tcl fs_dialog.tk helpcomm.tcl helplib.tcl hoc.tcl html_library.tcl libdm.tcl menu_override.tcl mouse.tcl vmath.tcl ) This list fails every time to terminate. However, if I comment out either the first or the second entry (but NOT other entries, although my testing has not been exhaustive) it DOES terminate. There is nothing special about either of the two first files that I can discover. Also, if I comment out one of those two and add another file, the termination failure returns. It's not terribly critical, but it is rather disturbing that these copy commands keep getting run when I can't see any reason for it. Has anybody seen behavior like this? How would I check what is triggering the copy? I can try to cook up a more minimal test case if there is a need, but it's difficult to be sure I can reproduce it in a contained test because I don't know for sure what's happening. Any help appreciated.
