Some comments:

The first versions of C were designed at pre-microcomputer times at Bell Labs, so the developers did not even think about microcomputers/controllers at that time. A long time ago, I was lucky to meet one of the first developers in Indiannapolis who did a very rudimentatry implementation of C for 8080/Z-80 based CP/M machines (ECO-C).

Nevertheless, in the following years, C (and its successors, like C++, and C#) has been established as a programming language for various hardware platforms including PCs, microprocessors, and microcontrollers. The only problem is that C for one platform is not like C for another platform because of the diferent structure of such platforms.

Doing a 

   printf("Hello World");

on one platform my nicely display this text on the console, where trying this with C dedicated for a microcontroller will do something completely different, like sending the string as serial output - maybe, printf() is not even implemented at all.

There are some C implementations for the SX available on the market but I must admit that I did not like any of those I had a look at, nore did I use them to generate any meaningful SX application.

I think you won't be lucky finding a version with an SX-specific header file that allows you to port the C code for the CMUCam you have on an SX w/o heavy work on the existing code. Therefore, I think you are better off to analyze how your code handles the camera, and the interfacing and then try to port this into assembly code, or into SX/B code.
