- Subject: [PATCH] ZZIP_LIBLATEST: create symlinks only if target is missing
- zzip/CMakeList.txt uses custom build targets to create symlinks to the
- (normally versioned) build results from unversioned file names. These
- targets are executed unconditionally, every time a build is started,
- regardless of the existence of the symlink.
- Debug builds, however, generate unversioned libraries. The build targets
- therefore overwrite existing files with recursive links.
- Create custom targets depending on the target file plus custom build
- commands containing the symlink creation, thereby ensuring that symlinks
- are only created if the link target is missing.
- Signed-off-by: Andreas Ziegler <br015@umbiko.net>
