I want to build the solver as a standalone binary (command-line tool). =
I'm using Mac OS X Mojave.

I downloaded and unpacked freecell-solver-5.0.0 and said:

    cd /Users/mattneubelcap/Downloads/freecell-solver-5.0.0=20
    cmake . -DFCS_WITH_TEST_SUITE=3DOFF

(Because I couldn't get the test stuff to build from cpan.)

What I got is:

--------

-- Configuring done
