WARNING: Target 'Code::Blocks - Autosave': Unable to resolve 1 external dependencies:
devel\libcodeblocks.a
This is non-critical. There are external dependencies setup in the project that cannot be resolved. You can check this in the project options -> external dependencies. Obviously wither the file does really not exist, or it has not been built yet, or the path/file name is simply wrong.
