+[CMake] Build failure with GCC 6 (fatal error: stdlib.h: No such file or directory)
+
+https://bugs.webkit.org/show_bug.cgi?id=161697
+
+Reviewed by Michael Catanzaro.
+
+Get the list of system includes from GCC and add it to the CMake
+list of implicit includes. This way, CMake will filter any of this
+directories from the list of includes when calling the compiler.
+
+This avoids an issue with GCC 6 that causes build failures when
+including the default include path as a system include (-isystem).
