Don't try to build a boost library outside of the super-project. It's not going to work.

Ungodly instructions at https://www.boost.org/doc/libs/1_68_0/libs/iostreams/doc/installation.html :

To build with Boost.Build, run b2 from the directory libs/iostreams/build, or from the Boost root directory.

made me do it. Why is it even provided as a separate project if you can't build it standalone :( Deities frown upon it.
