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.
