# Note: We explicitly set CMAKE_CXX_STANDARD=14 when compiling exiv2 because
# it uses `auto_ptr`, which has been removed in c++17. Clang 16 switches to
# using -std=c++17 by default, and that causes build failures with libc++.

# FIXME: Remove this setting when exiv2 has been updated to remove usage of
# `auto_ptr`, and also remove the workaround in `FindLibExiv2.cmake`.
