## Notes
If you encounter issues when linking wrt. c++11 symbols you might have run into GCC ABI incompatibility introduced from GCC 5.0 onwards. You can fix this by adding '-s compiler.libcxx=libstdc++11' to the conan call or changing compiler.libcxx to
```
compiler.libcxx=libstdc++11
```
in $HOME/.conan/profiles/default or run
```
conan profile update settings.compiler.libcxx=libstdc++11 default
