Как подключить файлы Gstreamer в QtCreator проект?

Question

Хотел посмотреть как работают библиотеки Gstremer в QtCreator. Хотел запустить примеры с сайта, но столкнулся с проблемой..

- Как правильно подключить библиотеки?

У меня выдает ошибки:

• LNK2019 unresolved external symbol g_clear_error referenced in function main

Так же подобные для: g_free, g_clear, g_print и тд.

• LNK1120 6 unresolved externals (что логично, у меня 6 ошибок :) )

Читал подобные вопросы и вроде даже разобрался с хитростями подключения, но ответ на этот вопрос не нашел.

ДЕТАЛИ:

QtCreator с компилятором Desktop Qt5.15.2 MSVC 2019 64-bit;

Gstreamer 1.18.1 (с сайта скачал: gstreamer-1.0-msvc-x86_64-1.18.1 и gstreamer-1.0-devel-msvc-x86_64-1.18.1), взял с одной рабочей open-source проги.
