+  Set the compiler version at build time.
+  The build system defines P4C_VERSION as a full string as well as the
+  following components: P4C_VERSION_MAJOR, P4C_VERSION_MINOR,
+  P4C_VERSION_PATCH, P4C_VERSION_RC, P4C_GIT_SHA and CMAKE_BUILD_TYPE.
+
+  They can be used to construct a version string as follows:
+  #define VERSION_STRING "@P4C_VERSION@"
+  or
+  #define VERSION_STRING "@P4C_VERSION_MAJOR@.@P4C_VERSION_MINOR@.@P4C_VERSION_PATCH@@P4C_VERSION_RC@"
+
+  Or, since this is backend specific, feel free to define other numbering
+  scheme.
