Hello everyone Excuse me I'm starting with the library libviso2 I try to compile viso2_ros to make visual mono odometry

But when I compile with the make command, I receive the following error:

Linking CXX executable bin/monoodometer /usr/bin/ld: ne peut trouver -lviso2 collect2: erreur: ld a retourné 1 code d'état d'exécution make[2]: *** [bin/monoodometer] Erreur 1 make[1]: *** [CMakeFiles/mono_odometer.dir/all] Erreur 2 make: *** [all] Erreur 2
