Я разработал программу на C ++ с использованием библиотек OpenCV и ITK, которую я создал с помощью cmake. Программа (xxx. cpp file) имеет 3 класса и основную функцию (для ввода и отображения вывода).
После этого я создал приложение формы windows, чтобы получать данные от GUI. Он производит два файла MainForm.h и MainForm. cpp.
Я новичок в C ++ и никогда не создавал GUI приложений на C ++. Я хочу включить мой внешний файл. cpp в GUI, чтобы при нажатии кнопки можно было вызывать функции из файла (xxx. cpp). Я выполнил действия, описанные в этой ссылке: https://mcn-www.jwu.ac.jp/~yokamoto/openwww/vsg/OpenCV/
Проблема в том, что я не могу найти решение для вызова функций из внешнего файла xxx. cpp. Я попытался скопировать код в MainForm. cpp, но произошли ошибки. Пожалуйста, помогите мне следовать правильной процедуре. Спасибо.
