Я не могу запустить проект CGAL, включая оболочку leda_real

Я пытаюсь скомпилировать эту маленькую программу:

Я установил CGAL в своей домашней папке и связал его в cmake-gui.

Я также скомпилировал свой CGAL, связав его с моим LEDA в cmake-gui. Это также в моей домашней папке.

Если я уберу строку ‘include leda_real.h’, программа будет работать отлично. Однако при включении я получаю следующую ошибку:

Вот как мой cmake-gui выглядит в обеих программах:

Я установил GMP, MPFR, Boost, libx11-dev, libqt4-dev и многие другие библиотеки, пытаясь заставить это работать, и у меня не получилось.

Пожалуйста. Мне действительно нужно, чтобы это работало. Если вам нужна какая-либо другая информация об этом, я с радостью предоставлю ее, если вам будет сказано, как это сделать

Я не знаю, как действовать дальше, и я потратил много времени на это. Больше, чем я хотел бы признать, учитывая мои скромные результаты. Я обнаружил, что моего первоначального подхода с использованием Quotient будет недостаточно для решения проблемы, так как мне нужно обрабатывать много sqrts. Я просто не могу заставить библиотеку работать.

Заранее благодарим за любую подсказку, которую вы можете предоставить!
