Would you like to work on fixing this bug ?

No. I wouldn't know where to start and look at

Reproduisez l’échec avec cmake -DCLANG_TIDY=ON .. et inspectez le build CMake/Hunter GTest montré dans le journal. Déterminez pourquoi les déclarations d’expressions régulières POSIX de GTest ne sont pas disponibles avec la toolchain C++ indiquée, puis vérifiez que la dépendance se construit correctement et que la configuration du projet s’achève sans les erreurs regex_t.
