build ===== sol2 is a header-only library. sol2 comes with a CMake script in the top level. It is primarily made for building and running the examples and tests, but it includes exported and configured targets (``sol2``, ``sol2_single``) for your use. ``sol2::sol2`` alias is defined for the ``sol2`` target as well. sol2 also comes with a Meson Script. If things stop working, file a bug report.
