Description:
If Bison version is 3.8.2:
...
-- Found BISON: /usr/local/opt/bison/bin/bison (found version "3.8.2") 
...
/Users/laurynas/vilniusdb/mysql-8.0.28/_build-tmp/sql/sql_yacc.cc:46159:1: error: unused label 'yyexhaustedlab' [-Werror,-Wunused-label]
yyexhaustedlab:
^~~~~~~~~~~~~~~

Compiler is AppleClang 13.0.0.13000029

How to repeat:
On macOS,

export PATH="/usr/local/opt/bison/bin:$PATH"
(obviously the workaround is "don't do that, then" - use /usr/bin/bison which is 2.3)

cmake ... -DMYSQL_MAINTAINER_MODE=ON
make
