Summary0014152: Comment change in flags.make triggers unnecessary rebuilds
DescriptionLet's say you have a set of source files and you use set_source_files_properties() to set COMPILER_DEFINITIONS on just one of those files. If you change that definition, it results in *all* the files getting rebuilt. This is because the makefile generator adds a comment to the flags.make file stating the custom define. The actual flags are unchanged, but because the comment changes, make rebuilds all the sources because those sources depend on the contents/timestamp of flags.make. I would recommend that the custom defines NOT be included in a comment within the flags.make file to avoid this. Maybe those comments can be sent to a separate file which has no effect on the build, since they are just informational anyway?
