ld не может найти libGL (16.04LTS x64 + драйвер Nvidia)

Я использовал update-alternatives выбрать nvidia-367 как поставщика для opengl.

Я выполнил ldconfig

Я проверил, что все символьные ссылки допустимы и указывающий на корректную папку ·

root@laptop:/etc/ld.so.conf.d# ls -halt
lrwxrwxrwx   1 root root  41 sep.   2 18:59 i386-linux-gnu_EGL.conf -> /etc/alternatives/i386-linux-gnu_egl_conf
lrwxrwxrwx   1 root root  40 sep.   2 18:59 i386-linux-gnu_GL.conf -> /etc/alternatives/i386-linux-gnu_gl_conf
lrwxrwxrwx   1 root root  43 sep.   2 18:59 x86_64-linux-gnu_EGL.conf -> /etc/alternatives/x86_64-linux-gnu_egl_conf
lrwxrwxrwx   1 root root  42 sep.   2 18:59 x86_64-linux-gnu_GL.conf -> /etc/alternatives/x86_64-linux-gnu_gl_conf

root@laptop:/etc/alternatives# cat x86_64-linux-gnu_gl_conf 
/usr/lib/nvidia-367
/usr/lib32/nvidia-367

но все еще когда я передаю -Wl,--verbose к g ++ во время сборки моего проекта, я получаю следующее:

Как Вы видите, нет никакого упоминания о папке nvidia-367 нигде, даже если конфигурация ld ясно настроена для рассмотрения ее.

Что дает?
