Fix build issues with PIPEDAL_DISABLE_COPYRIGHT_BUILD

- Wrap notices.txt install in if(NOT PIPEDAL_DISABLE_COPYRIGHT_BUILD)
  so the install doesn't fail when copyright generation is skipped.

- Add explicit install rules for libSQLiteCpp.so.0, libsqlite3.so,
  and libzip.so.5. These are built from submodules but their own
  install targets are suppressed (SQLITECPP_INSTALL=OFF,
  LIBZIP_DO_INSTALL=OFF), so they were never copied to /usr/lib,
  causing 'cannot open shared object file' errors on distros
  without these as system packages (e.g. Arch vs Ubuntu).
