That's not really true... objects get built into <target_name>.dir ... so they are different. the problem is cmake only maintains a single list of sources, and the flags end up getting set for both versions. Really have to use target_properties ... or somehow invent a way to set_target_source_files_properties( target source .... ) maybe seperate the sources that need different flags into another library, and apply said flags to that target.. then link the whole mess together? > HTH, > Marcel Loose. > > On Fri, 2010-10-01 at 17:10 +0200, pellegrini wrote: >> Hi Ryan, >> >> Yes, that might be the solution if I wanted to change the compiler flags >> for the whole library but in my case, that is not on the whole >> library that I want to apply a new set of compiler flags but only on a >> small number of files. >> >> Ryan Pavlik a écrit : >> > Look at the target properties instead of the source file properties. >> > >> > Ryan >> > >> > On 10/01/2010 08:27 AM, pellegrini wrote: >> >> Hello everybody, >> >> >> >> I would like to build two libraries that contain the same files but >> >> with a slightly different set of compilation flags >> >> from one library to another.
