GLEW won't work with CMAKE - c++

Question

I'm trying to write a simple program with GLFW and GLEW, and while I could successfully add the needed GLFW libraries I can't do the same with the GLEW ones.
I'm totally new to CMAKE so I don't know what I should do differently. I am using CLion btw. Thanks in advance!
cmake_minimum_required(VERSION 3.3)
project(OpenGLHelloWorld)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp)
add_executable(OpenGLHelloWorld ${SOURCE_FILES})
add_subdirectory(../glfw-3.1.2 ${CMAKE_CURRENT_BINARY_DIR}/glfw_bin)
include_directories(../glfw-3.1.2/include)
target_link_libraries(OpenGLHelloWorld glfw ${GLFW_LIBRARIES})
ADD_DEFINITIONS(-DGLEW_STATIC)
include_directories(../glew-1.13.0/include)
link_libraries(../glew-1.13.0/lib)
And the cpp file:
#include <GL/glew.h>
#include <GLFW/glfw3.h>
#include <stdio.h>
using namespace std;
int main() {
if(!glewInit()) {
fprintf(stderr, "Could not start GLFW3\n");
}
return 0;
}
And the error:
undefined reference to `glewInit#0'

Answer 1

You didn't link your compiled code to glew.
target_link_libraries(OpenGLHelloWorld glfw ${GLFW_LIBRARIES} GLEW)
That should fix glew lib linking to your executable.
HTH.
