+Subject: [PATCH] cmake: expand DTC version regex
+
+DTC can be built with both traditional Makefiles or Meson. When built
+with Makefiles the --version output looks like 'Version: DTC
+1.6.1-dirty' but when built with Meson the output is 'Version: DTC
+v1.6.1+.
+
+This fails to match the version regex and the cmake then fails:
+
+CMake Error at cmake/host-tools.cmake:28 (if):
+  if given arguments:
+    "VERSION_GREATER" "1.4.6"
+  Unknown arguments specified
+
+Expanding the regex with an optional 'v' covers both cases and the build
+succeeds.
