Answer 1

This is how i fixed this headache:
Downloaded 32 bit of glfw binaries (even though i am on 64 bit machine)
Renamed and Copy pasted selected files from the binaries in my project like this:
modified my CMakeLists.txt like this:
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)
