We should probably tell the user that he can install Visp other dependencies here, even if they are optional for compiling Visp. This would solve the missing X11 library error we encounter just next, so at least this one should be installed.
May be something like:

- At this point, you can also install ViSP other dependencies using conda depending on which features you want to be compiled. You will need to install at least the X11 libraries:
     (visp-conda-ws) $ conda install xorg-libx11
  
  However, we recommend this minimal set of dependencies to get the main features of ViSP available:
     (visp-conda-ws) $ conda install xorg-libx11 eigen libopencv libjpeg-turbo libpng
