X-Git-Tag: cvc5-1.0.0~808
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d4183fd0318585e089e805e97f8123cd8f84ace5;p=cvc5.git

Update Python packaging infrastructure (#7654)

- Stop passing --lib-only (it no longer exists)
- Fix the regex search for the cvc5 version
- Take a version suffix as an (optional) environmental variable

+# The suffix should start with a letter, and end with a number
