+
+Обязательные параметры: `NAME` - имя библиотеки и `TYPE` - тип цели.
+Параметр `OUTPUT_NAME` определяет базовое имя выходных файлов.
+Параметр `EXPORT_FILE_NAME` задаёт имя заголовочного файла экспортируемых
+переменных, а `EXPORT_BASE_NAME` - базовый суффикс для формирования имён переменных.
+Все остальные параметры передаются в стандартную функцию `add_library()`
