This is\na backwards compatibility feature.\nIf you want the library to produce ColumnBool, set the CMake variable `DCH_MAP_BOOL_TO_UINT8=OFF`.\nThe default for this variable will switch, with it being subsequently removed, in\na future release.\n\n## Dependencies\nIn the most basic case one needs only:\n- a C++-17-complaint compiler,\n- `cmake` (3.12 or newer), and\n- `ninja`\n\nOptional dependencies:\n- openssl\n- liblz4\n- libabs",
