This is primarily to allow using LibUnicode within LibJS and its REPL. Note: this seems to be the first time that a Lagom dependency requires generated source files. For this to work, some of Lagom's CMakeLists.txt commands needed to be re-organized to include the CMake files that fetch and parse UnicodeData.txt. The paths required to invoke the generator also differ depending on what is currently building (SerenityOS vs. Lagom as part of the Serenity build vs. a standalone Lagom build).
