sqlitemap is header-only and can be used from CMake via:

  find_path(SQLITEMAP_INCLUDE_DIRS "bw/sqlitemap/sqlitemap.hpp")
  target_include_directories(main PRIVATE ${SQLITEMAP_INCLUDE_DIRS})

However it requires

  find_package(unofficial-sqlite3 CONFIG REQUIRED)
  target_link_libraries(main PRIVATE unofficial::sqlite3::sqlite3)
