Мобильная версияЯ относительно новичок в C++, поэтому, возможно, мне не хватает некоторых ключевых моментов, касающихся использования ссылок, особенно в таком сложном проекте.
Я могу собрать OpenSSL 3.4.0 хорошо, поскольку нам нужна статически связанная библиотека в POCO, которая, в свою очередь, будет статически связана с нашим двоичным файлом. Однако при сборке и связывании его с POCO 1.13.3 мы получаем 160 неразрешенных внешних символов при связывании POCO::Crypto, причем все они являются символами, которые должны быть предоставлены OpenSSL. Компиляция прошла успешно, но при компоновке произошел сбой.
При этом используются базовые выпуски POCO и OpenSSL из git и используется стандартная установка Visual C++ 2022 со встроенным vcxproj POCO.

Эта система сборки работает на других машинах, но не на этой, и непонятно почему. Чего не хватает, чтобы статически связать эти две библиотеки для проекта? Мой коллега предоставил мне предварительно связанные библиотеки для POCO, но это не позволяет мне постоянно создавать проект с нуля.
