I can confirm this fixes the reported issue. I can also confirm that LibArchive is found properly with xenial- backports enabled:
estan@newton:~/tmp$ cat CMakeLists.txt find_package(LibArchive) estan@newton:~/tmp$ cmake . . . . -- Found LibArchive: /usr/lib/x86_64-linux-gnu/libarchive.so (found version "3.1.2") . . . estan@newton:~/tmp$ Thanks a lot for fixing this so fast! No-op builds are now next to instantaneous, even with AUTORCC-generated sources, as they should be :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1624832 Title: [SRU] AUTORCC-generated resources always out-of-date with Ninja To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cmake/+bug/1624832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
