-Here is a minimal working example. It tests the inline keyword, then __inline__ and then __inline. When it finds one that works, it will ADD_DEFINITIONS(-Dinline=${KEYWORD}) and if none work, it will ADD_DEFINITIONS(-Dinline=).

-# Inspired from /usr/share/autoconf/autoconf/c.m4
-FOREACH(KEYWORD "inline" "__inline__" "__inline")
-   IF(NOT DEFINED C_INLINE)
-     TRY_COMPILE(C_HAS_${KEYWORD} "${GPUIT_BINARY_DIR}"
-       "${GPUIT_SOURCE_DIR}/test_inline.c"
-       COMPILE_DEFINITIONS "-Dinline=${KEYWORD}")
-     IF(C_HAS_${KEYWORD})
-       SET(C_INLINE TRUE)
-       ADD_DEFINITIONS("-Dinline=${KEYWORD}")
-     ENDIF(C_HAS_${KEYWORD})
-   ENDIF(NOT DEFINED C_INLINE)
-ENDFOREACH(KEYWORD)
-IF(NOT DEFINED C_INLINE)
-   ADD_DEFINITIONS("-Dinline=")
-ENDIF(NOT DEFINED C_INLINE)

-You also need this file in your source directory.
