CMake is functions/macros are case-insensitive (unlike variables), but names differing only by case (e.g. "BuildLuaJit" instead of "BuildLuajit") may look the same at a glance. This can be confusing if you do a case-sensitive search, such as by using the * key in neovim to search for other instances of the word under the cursor.
