The previous commit meant to avoid adding an LDFLAG but it just avoided the issue. The real issue is PNG_BUILD_ZLIB being turned to ON. This variable is for specifying a custom zlib location, which is not necessary. Switching it to OFF calls find_package and links properly. Backported two zlib related patches. The latter is a somewhat impoarant fix. Signed-off-by: Rosen Penev <rosenp@gmail.com> |
