G++, SDL Compilation problem (compiler does not see the library)

Question

after updating g++ to 11.2.0 (before that I had a very old version), I can't compile my project with the same command. For some reason, the compiler cannot find the sdl library, although everything worked fine before.

C:\Users\*****\Desktop\****>g++ -I/src/include -L/src/lib -o main main.cpp -lmingw32 -lSDL2_ttf -lSDL2main -lSDL2 -lSDL2_image
main.cpp:5:10: fatal error: SDL2/SDL.h: No such file or directory
    5 | #include <SDL2/SDL.h>
      |          ^~~~~~~~~~~~
compilation terminated.

I also tried to use the local path, but still unsuccessful. Then it gives me this error.

C:\Users\*****\Desktop\*****>g++ -Isrc/include -Lsrc/lib -o main main.cpp -lmingw32 -lSDL2_ttf -lSDL2main -lSDL2 -lSDL2_image
