OpenCV just won't run on Code::Blocks [closed]

edit

Hello,

each time I run default program, it just refuses to run.

In function `main':
C:/opencv/buld_cb/wedwedwe/main.cpp:8: undefined reference to `cv::imread(cv::String const&, int)'
C:/opencv/buld_cb/wedwedwe/main.cpp:11: undefined reference to `cv::namedWindow(cv::String const&, int)'

I'm new to OpenCV and to C++ in general so I have almost no clue what to do. I tried to follow manuals, I did this stuff with CMake building (where I had to delete some AVX stuff in GPU_DISPATCH and then completly disable Python features, because it just won't set up in Code::Blocks either way) and MinGW building after that.

I have paths in my Windows 10 OS for C:\TDM-GCC-64\bin, C:\Program Files\TortoiseGit\bin, C:\Program Files\Git\cmd, C:\Program Files\CMake\bin, C:\MinGW\bin, C:\opencv\buld_cb\bin

In search directories, as a compiler I have C:\opencv\buld_cb\install\include\opencv2, and as a linker I have C:\opencv\buld_cb\lib, both in Debug and Realise. In linker settings, I have all those .a files from C:\opencv\buld_cb\lib

When I make new OpenCV project with such settings as in picture and try to run a default code, it just refuses to do so with errors I copypasted earlier.

I actually managed to launch OpenCV in Code::Blocks somehow, but I have no clue what to do now to run a program. Help please, thanks.
