-В случае получения ошибок вида `error: variable 'y' set but not used [-Werror,-Wunused-but-set-variable]` ножно попробовать использовать другую версию компилятора сlang. Например, на момент написания данного текста описанная выше команда по установке clang для Ubuntu 20.04 по-умолчанию устанавливает clang-13, с которым возникает эта ошибка. Для решения проблемы можно установить clang-12 с помощью команд:
-```bash
-wget https://apt.llvm.org/llvm.sh
-chmod +x llvm.sh
-sudo ./llvm.sh 12
-```
-И далее использовать именно его, указав соответствующую версию при установке переменных окружения CC и CXX перед вызовом cmake.
