Построение плагина Mosquitto MQTT auth

Question

Мне нужен продвинутый аутентификатор для Mosquitto. Я решил использовать Mosquitto-Auth-Plug

Однако, если я буду следовать инструкциям по сборке, у меня будет ошибка:

$ make
Selected backends:          JWT
Using mosquitto source dir: /mnt/c/Users/avkar/cleversky/mosquitto/mosquitto-1.4.15
OpenSSL install dir:

If you changed the backend selection, you might need to 'make clean' first

В некотором роде -lmosquitto не найдено. Я предположил, что это библиотека, но присутствуют все библиотеки:

$ ls ../mosquitto-1.4.15/lib/

Что -lmosquitto и как я могу исправить мою сборку?

Answer 1

Как выяснилось в комментариях,

Вам нужно собрать и установить mosquitto (или установить предварительно собранную версию и ее пакет разработчика), прежде чем пытаться собрать плагин.

Ошибка в том, что ld не может найти libmosquitto для ссылки
