I can't seem to reproduce the behavior you reported. Here are the steps I took and what I observed:
- I imported your project into CCS 5.4
- Changed the build configuration from Debug to Release
- Went into Project Properties->CCS Build->ARM Linker->File Search Path and added a library under the --library option field, clicked OK
- Went back into Project Properties and the lib file was still there
So I don't see any issues with either adding libraries or them being retained.
One comment is that the libraries have to set each time you go to a new build configuration (for instance the first time you change from Debug to Release, or even if you create a new build configuration), however once it has been changed/set it should be retained.
Unfortunately there may not be much more we can do without being able to reproduce the issue. Based on the steps I described above, if I need to do something different to see the behavior please let me know.
