SQLite is another package that many people will have installed (firefox uses it, for example) and that has few dependencies in Sage (only readline).

libsqlite3 is used by Python during its build. Some Python packages need sufficiently new versions. We set the lower bound slightly lower than the current version available on XCode.

We detect it using AC_RUN_IFELSE because on macOS without homebrew, there is no pkgconfig file.
