C++17 std::filesystem instead of boost

[paamand]

Can we use std::filesystem (in c++17) instead of Boost::filesystem?

I'm having problems because of this

Can we use std::filesystem (in c++17) instead of Boost::filesystem?

of course you can, just use cmake -DWITH_BOOST=OFF .. when configuring the project

Also got coredump on Arch after some first experiments in the cpp-dependecies directory.
With 'cmake -DWITH_BOOST=OFF' even compilation failed (error: ‘strstr’ was not declared in this scope)

Seeing this still as well
