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.
|
||
