opencv_viz is required but was not found

[daalberti1]

Hi, I'm working inside an Anaconda virtual environment trying to install the software with source setup.sh -a, but i get the following output :

CMake Error at /home/davide/miniconda3/envs/sobfuEnv/share/OpenCV/OpenCVConfig.cmake:205 (message):
opencv_viz is required but was not found
Call Stack (most recent call first):
CMakeLists.txt:32 (find_package)
-- Configuring incomplete, errors occurred!

These are some of the package's versions I've installed with conda install:
boost: 1.67
cuda: 9.1
opencv: 2.4.11
pcl: 1.8.1
vtk: 6.3
