Compiling SDL2 + OpenGL + GLAD project in Code::Blocks on Windows: undefined references

I'm checking different variants of creating windows applications that use OpenGL code. I'm especially interested in OpenGL Core Profile (so called "modern OpenGL"). I'm using Code::Blocks as my IDE.

At first I coded a simple WinAPI application. It worked fine, until I tried to run some Core code. This showed me if I want to use modern OpenGL in Windows, WinAPI is not of use here, because it's fixed with Immediate mode.

So, my next step was to make a project using GLFW + GLAD (which is generated on https://glad.dav1d.de/ site). During this approach there was some unresolved symbols to OpenGL functions, but GLAD fixed this and my project was finished. Compile & Run without problems.

This time I want to test a SDL variant. I downloaded SDL2 headers and libraries and put them into right folders in C::B installation. At first I coded a simple SDL2 only application and it worked fine, which showed me that includes and links to libraries in the build options doesn't gets the compiler to choke with my code.

Now I added some code which uses opengl's core functions. At first compiling that code resulted in the compiler complaining about those functions. I resolved them by again adding GLAD, just like with my previous project, and it works fine, but only compiling. When trying to link my program, the compiler spits out a lots of these errors:

I'm pretty sure I messed something in linking libraries. Maybe they are in the wrong order. Maybe I miss some. ORit may be another error enterly.

My library list in linkier options is:

mingw32SDL2mainSDL2glew32opengl32glu32

I don't know from what library is "__imp_SetupDiGetClassDevsA" and its company and thus I don't know what to do ☹.
