+Subject: [PATCH] Build: update cmake minimum version to 3.10
+
+cmake ABI compatibility with cmake <3.5 has been removed in cmake 4.
+Compatibility with cmake <3.10 is deprecated and soon to be removed.
+Thus set 3.10 minimum version. This is available in the vast majority
+of current linux distributions, as well as other platforms.
