codeblocks can't find my compiler

OK, so I downloaded Codeblocks and I already have a cygwin terminal on my computer that I regularly use to compile and run C programs, but when I try to build a program in CodeBlocks, it gives me an error:

The compiler's setup (GNU GCC Compiler) is invalid, so Code::Blocks cannot find/run the compiler.

I don't know why it can't find my compiler or why it's looking for GNU GCC compiler when I have Cygwin GCC as the default compiler.
