This should've been done automatically. See config.h.cmake, it has

  /* Define to `__inline__' or `__inline' if that's what the C compiler calls
   it, or to nothing if 'inline' is not supported under any name.  */
  #cmakedefine C_HAS_inline 1
  #if !(C_HAS_inline)
  #ifndef __cplusplus
  # define inline @C_INLINE@

and @C_INLINE@ should've been __inline in your case

because the variable AIX is not defined in our cmakefiles.
If you grep for AIX, you'll see the following test:


I hope it'll work for you.
