single line regex to get current version in cmake script

[hitsmaxft]

orgin cmake script's CMAKE_GIT_REPO_VERSION paring sometimes not working properly . here is my regex rewriting
do version in single regex with regex grouping

example of output from cmake -B build on my branch

PICO_SDK_PATH is /home/wsl/projects/gp2040ce/pico-sdk
PICO platform is rp2040.
GIT_REPO_VERSION is v0.7.6-6-g40721a4
CMAKE_GIT_REPO_VERSION is 0.7.6
Submodules updated

The goal of main's version is to produce v0.7.6.6 for your example. What error are you seeing?

output fallbakc to 0.0.0

I will upgrade regex to support 0.7.6.6

[bsstephan]

That would be good. I have seen a surprising incidence rate of the 0.0.0 output so I can believe my successive hacks are causing a problem. If you get the regex to match to 0.7.6.6 in your example, this will probably be mergeable.

looks good, this catches all of the scenarios I can think of
