How do you change the build options?

[j0h]

I am compiling SDL programs, and I want to add some SDL libraries.
I have already selected  an SDL project type, which will compile successfully.
but if i then want to add 

Code

<SDL/SDL_image>

the compiler will then not build properly.
I am 100% certain this is directly realted to the build flags in use, and that if I could give codeblocks the command

Code

g++ -Wall -o "%e" "%f" -lSDL -lSDL_image

  to specify compiling with the SDL_Image library,
that my problems would be resolved. I can compile just fine in the terminal, and run.
I asked on stackexchange, but no one has gotten back to me yet.
I have clicked around int the IDE, but I haven't seen any place to modify or include additional build flags.

Then you haven't clicked good enougth
For the compiler:
Project->Build options->Other compiler options
For the Linler
Project->Build options->Linker settings->Other linker options
