Install prerequisites

First, go to http://brew.sh to install Homebrew.

Install ViSP with homebrew

To get information on ViSP package:

$ brew update
$ brew info visp

To install ViSP and additional dependencies (cmake, opencv3, libdc1304, gsl, zbar, x11), just run:

$ brew update
$ brew install visp

Tips and tricks

How to install visp from source

To build and install ViSP from source with homebrew you may run:

$ brew install visp --build-from-source

How to uninstall visp formula

$ brew remove visp

/usr/local/include/visp is not writable

If during ViSP installation you get the following error

$ brew install visp
...
==> Pouring visp-3.0.0.el_capitan.bottle.tar.gz
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink include/visp/visp_modules.h
/usr/local/include/visp is not writable.

You can try again using:
  brew link visp
...

it means maybe that you install other softwares without brew in /usr/local. A work around is to change the owner of the corresponding folder like:

$ sudo chown {your-user-name} /usr/local/include
