How to use Recast library?

[shahbazsiddique69]

hello guys!
I have built the UE4 editor with carla0.9.15. But can anyone tell me how to use recast navigation library ?
I want to edit the navigation meshes of pedestrians and make them jaywalk/walk on roads.
In my carla\build\recast\RecastDemo\Bin there is no recast.exe.
I downloaded the recast-navigation library from github, and didn't find it there as well.
By default, they are only walking on sidewalks and using crosswalks for crossing roads. I have seen that for crossing roads, the set_cross_function is already set in my program.
N.B. I am using carla town_10 in carla0.9.15
