Я не помню, как был установлен boost, и моя ОС - Ubuntu 14.04.

Итак, мои вопросы:

1. Какой метод следует использовать для обнаружения наличия библиотеки в системе?

2. Как полностью удалить библиотеку наддува?

ОБНОВИТЬ:

Кажется, мне удалось сделать это, как здесь, но не уверен, что это хороший способ и apt list --installed | grep boost, ldconfig -p | grep boost все еще показывают наличие наддува:

rm /usr/local/lib/libboost*
sudo rm -r /usr/local/include/boost
