+# From  http://www.cmake.org/Wiki/CMakeCompareVersionStrings

+# Computes the realtionship between two version strings.  A version
+# string is a number delineated by '.'s such as 1.3.2 and 0.99.9.1.
+# You can feed version strings with different number of dot versions,
+# and the shorter version number will be padded with zeros: 9.2 <
+# 9.2.1 will actually compare 9.2.0 < 9.2.1.
+#
+# Input: a_in - value, not variable
+#        b_in - value, not variable
+#        result_out - variable with value:
+#                         -1 : a_in <  b_in
+#                          0 : a_in == b_in
+#                          1 : a_in >  b_in
