Невозможно скомпилировать минимальный образец wxWidgets с CMake - PullRequest

/ 30 декабря 2018

Я пытаюсь преобразовать SFML-приложение в wxWidgets.Я создаю wxWidgets и запускаю минимальный пример в соответствии с этой веткой: Как настроить wxWidgets 3.1.0 с Visual Studio 2015

Он отлично работает, когда я использую Visual Studio с соответствующим решением,но когда я пытаюсь использовать данный файл CMakeLists.txt для генерации решения с помощью CMake, это решение не работает, выдавая ошибку ссылки:

error LNK2019: symbole externe non résolu "public: static void __cdecl _WX_LIST_HELPER_wxMenuItemList::DeleteFunction(class wxMenuItem *)" (?DeleteFunction@_WX_LIST_HELPER_wxMenuItemList@@SAXPEAVwxMenuItem@@@Z) référencé dans la fonction "public: __cdecl wxMenuItemList::~wxMenuItemList(void)" (??1wxMenuItemList@@QEAA@XZ)

Это должно быть понятно даже на французском языке.Я искал везде и не могу заставить его работать, поэтому здесь я прошу вашей помощи.

Я также попытался сравнить свойства обоих решений и сделать их как можно более похожими, но все равно это не такработает.

Спасибо.

РЕДАКТИРОВАТЬ: Хорошо пометить как дубликат, но это не объясняет мне, почему он работает с данным решением, но не с решением, созданным CMake, или чтоРазница и как ее устранить.

EDIT2: Вот CMakeLists.txt:
