    3232Download the precompiled 32bit binaries of GLFW and GLEW. Create lib/ and
    33 include/ folders in the root opengl-game directory you cloned. Copy the include/GL/ and include/GLFW/ folders into your include/ folder and all the files in
    34 the lib/ folders of the GLFW and GLEW libraries into your lib/ folder. Also
    35 copy the .dll files into the root opengl-game directory. This should be enough
    36 to compile and run the project.
     33include/ folders in the root opengl-game directory you cloned.
     34Copy the include/GL/ and include/GLFW/ folders into your include/ folder.
    3735
    38 I would like to figure out how to statically compile glew and glfw to eliminate the need for the dlls.
     36For GLEW, copy lib/RELEASE/Win32/glew32s.lib into your lib folder.
     37For GLFW, copy lib-vc2015/glfw3.lib into your lib folder.
     38
     39Download GLM and copy the glm folder (the one with all the .hpp files) into the include/ folder you made above.
     40GLM is a header-only library, so there is nothing to copy into the lib/ folder.
     41
     42Open and run NewOpenGLGame.sln in Visual Studio 2017 and run it.
