Solução

O CMake basicamente verifica se você tem o pacote Python wx instalado.

Para instalá-lo, use

install_wxpython.sh

pip install --user --break-system-packages wxpython

pip install --user --break-system-packages wxpython

Se isso não funcionar, verifique se você tem múltiplas versões do Python instaladas
