Confusion about using Faber to Build

Hi,

I'm trying to build the library (Ubuntu 20.04, Python 3.7 installed from Deadsnakes, Boost installed from Aptitude). When I clone the repo and run Faber, the build seems to succeed.

When I run `faber test.report`, most of the tests pass. I get the following

`test summary: 85 passes, 4 expected failures, 3 skipped`

But, when I try to link against this from my other project--a project that uses the typical CMake search function--it can't find the library. Is there some install command I need to run in order to put the binary in the right place? Something similar to `make install`? I see the binary inside the repo at `src/g++-9/x86_64/shared/libboost_python37.so`

Thanks!

Start by reproducing `faber test.report` on Ubuntu 20.04 and inspect the generated `src/g++-9/x86_64/shared/libboost_python37.so` path. Check the repository's Faber build targets and existing usage guidance for an install step or CMake-compatible location. Done means documenting the required command and how another CMake project can find the built library.
