Dear list, I need to run a tool after building an executable, which will modify the executable itself. I intend to extend the toolchain for this, because it shall be done for every executable on this particular operating system.
I think for this purpose, I need to change the rule CMAKE_<LANG>_LINK_EXECUTABLE. And I think I can't put multiple commands into that rule, so I need to write a wrapper which will be called instead of the normal linker, and the calls the normal linker and then that special tool. Right, so far? Now I'd like to pass a few additional parameters to this tool, which I'd like to get from a special target property. The rule currently looks like this: set(CMAKE_C_LINK_EXECUTABLE "<CMAKE_C_COMPILER> <FLAGS> <CMAKE_C_LINK_FLAGS> <LINK_FLAGS> <OBJECTS> -o <TARGET> <LINK_LIBRARIES>") And I wonder what these placeholders in angle brackets mean, and if there are more placeholders available. The manual doesn't say anything about this, unfortunately: https://cmake.org/cmake/help/latest/variable/CMAKE_LANG_LINK_EXECUTABLE.html Is there, for example, a way to access arbitrary target properties? Or do I need to hide my special parameters somewhere in the LINK_OPTIONS property? Regards, Sebastian
