Answer 1

This is how i fixed this headache:

1. Downloaded 32 bit of glfw binaries (even though i am on 64 bit machine)

2. Renamed and Copy pasted selected files from the binaries in my project like this:

3. modified my CMakeLists.txt like this:

4. build and hit Run!

Answer 2

Add the following at the end of the CMakeLists.txt

find_package(glfw3 REQUIRED )
target_link_libraries(projectname  GL glfw)
