It finds its own headers relative to the executable that the libraries
are compiled into, but the executable must be inside a specific
directory structure. If you just build from source then the
executables produced by the build (e.g. in `Release+Asserts/bin/`) are
already in the right directory structure.

What I usually do is add the build directory's bin/ to my PATH
whenever I want to use the freshly built one, and have my default PATH
use the system one.
