A missing lib

Good evening everyone, I'm new and I just signed up on the forum because I would like to create a virtual reality application. I code in C and C ++ for several years and I use SDL2 and OpenGL, I found on this site a link to an SDK that would meet my expectations and a sample code. I have included all the .h files and added the only supplied .lib file ("LibOVR.lib") but the compilation fails from the first function called (ovr_Initialize ()), there is probably a lib missing in the SDK provided because the software (Code :: Blocks) tells me "undefined reference", so I would like to know if among you there are people who have already been confronted with this problem and how she was able to solve this.

Thanks in advance.
