Как изменить параметр qtconfig в 'cmake' на qtconfig4?

Question

При настройке krita, я получаю сообщение cmake с сообщением Unable to compile a basic Qt application. Qt has not been found correctly. Я думаю, что причина в том, что существует конфликт между пакетами QT5 и QT4 dev. Что делать?

Я не уверен, но, возможно, причина в том, что он QT5, но KDE4 требует QT4. Я установил необходимые библиотеки libqt4, но это не поможет. Что мне делать?

Скажите, пожалуйста, если я ошибаюсь в ошибках.

Answer 1

Вы можете использовать переменную env QT_SELECT. (APT-получить установку qtchooser)

Пример

export QT_SELECT=4 

или

export QT_SELECT=qt4 

Answer 2

export QT_SELECT=4 и export QT_SELECT=qt больше не похоже на работу в cmake 2.8.12.2, переменные должны быть cmake переменные, т.е. пробег

cmake . -DQT_QT_INCLUDE_DIR=/usr/include/qt4/ -DQT_SELECT=4 
make 

для компиляции
