GLEW not listed in cmake dependencies

[norlesh]

Attempting to build under Visual Studio 2017 with both Eigen3 and Pangolin installed in my environment using Microsofts vcpkg source code package manager and while I was able to point CMake to there installed directories my build subsequently failed because GLEW was not found (specifically GL/glew.h) even though it is installed in the vcpkg system so I suppose for now I am going to need to update the project files by hand. I have posted a request to the vcpkg developers that they include support for Cilantro in the package manager which would mean a lot more cross platform use of your library under Visual Studio and am sure it would make there job a lot easier with the way the software works if that dependency was made explicit in the CMakeLists file.

Hi,

Thank you for the vcpkg port attempt!

It seems that GLEW include dirs should automatically become part of Pangolin's include dirs (please see USER_INC CMake variable usage in https://github.com/stevenlovegrove/Pangolin/blob/master/src/CMakeLists.txt and https://github.com/stevenlovegrove/Pangolin/blob/master/src/PangolinConfig.cmake.in).

Does the error occur even on regular (e.g. non-vcpkg) CMake builds?
