Unable to compile on Ubuntu 22.04 about curaengine

[jellespijker]

try updating gnu-gcc to version 13 or higher

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt install g++-13 gcc-13 -y
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-13 13
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-13 13

run conan profile detection again such that it uses the gcc-13

conan profile new default --detect --force

I will update the conanfiles such that the will fail with gcc-12 or lower

I figured out how to build it with GCC 12:

CONAN_CONFIG_VERSION='d79fe6fe1878f09b583e04b873544cec65cbac99' && conan config install https://github.com/Ultimaker/conan-config/archive/${CONAN_CONFIG_VERSION}.zip
conan profile new default --detect --force
conan profile update settings.compiler.libcxx=libstdc++11 default
conan profile update settings.compiler.cppstd=gnu20 default

The last line is most important.
