Linking GLEW with CMake

Question

How can you link GLEW to a project with CMake?

We\'ve been trying to link GLEW to our project using CMake for at least 3 hours without any success so any help is acc

Answer 1

I was struggling hard to link glew to cmake through command line on mac. This might be helpful but I am not sure :) I will walk you through step by step of what I have done.

I installed Cmake source from the web.

Then I went inside the cmake folder in terminal and typed

./bootstrap && make && make install 

(this will install cmake command line tools on our OS platform)

I have some exercise files. I want cmake to generate xcode files for me for all those exercise files (ex. triangles.cpp, shader.cpp etc) So i made a directory inside exercise files folder.

$ mkdir xcode 
$ cd xcode
$ cmake -G "Xcode" ..

At this point, Cmake suppose to install all xcode files that included correct libraries. But there was an error :

$ cmake -G "Xcode" ..
CMake Warning (dev) at CMakeLists.txt:3 (cmake_minimum_required):
Compatibility with CMake < 2.4 is not supported by CMake >= 3.0.
This warning is for project developers.  Use -Wno-dev to suppress it.

system name is: Darwin-14.1.0
system processor is: x86_64
-- Could NOT find GLEW (missing:  GLEW_INCLUDE_DIR GLEW_LIBRARY) 
-- Could NOT find Doxygen (missing:  DOXYGEN_EXECUTABLE) 
-- Using Cocoa for window creation
-- Using NSGL for context creation
-- Building GLFW only for the native architecture

CMake Error: The following variables are used in this project, but they are  set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
GLEW_LIBRARY
linked by target "TextureLoader" in directory /Users/Mydir/Desktop/Exercise/Exercise Files

-- Configuring incomplete, errors occurred!

Then to make sure I have installed GLEW and all its libraries correctly, I ran

$brew install glew 

Yes, I have installed glew already but it was NOT linked. See the Warning below:

Warning: glew-1.12.0 already installed, it's just not linked

Then I ran the following commands:

$ brew unlink glew 
$ brew link glew

And I have solved the error. So just make sure that you have linked glew. Hope this helps.

Happy Coding :)
