The FindX11 cmake module finds XRender for you.

So, in your project CMakeLists.txt, add the lines:
  if(X11_Xrender_FOUND)
    add_definitions(-DHAVE_XRENDER)
     target_link_libraries(foo ${X11_Xrender_LIB})
  endif(X11_Xrender_FOUND)

Finally, put conditional compiles in your source code:
#if defined(HAVE_XRENDER)
#include <X11/extensions/Xrender.h>
  ...and other xrender specific stuff
#endif
