Hi all- I'm building an executable using the standard command:
add_executable(MyExe a.c b.c) I'm adjusting the CMAKE_EXE_LINKER_FLAGS to emit a mapfile, and it works. If I delete the mapfile, though, performing an incremental build doesn't regenerate the mapfile. This makes sense, since I haven't expressed to cmake that the mapfile depends on MyExe. In the above scenario, the MyExe.map isn't even a target, so cmake doesn't even know it exists. I've tried creating a custom target, but I can't create a custom command that regenerates the mapfile, since it comes from add_executable. I then tried to use add_dependencies(), but that seems to only influence the build order. I could explicitly re-run the linker as a custom command that builds a custom target, but that seems wasteful since linking does take a bit of time. It almost seems like I need some way to tell add_executable that there are more outputs than just the executable image. Is there a way to do this? If anybody could point me in the right direction, I'd appreciate it! Thanks in advance for reading. Best, Charles
