  2. `attrs.c` - Assign the string value of the attribute. Of course this must be unique. And then assign a `function` to verify the attribute value. There are already a considerable number of defined functions to verify specific attribute values, but maybe this new attribute requires a new function, so that should be written, and defined.

  3. `attrdict.c` - If this attribute only relates to specific tags, then it should be added to their list. There are some general attributes that are allowed on every, or most tags, so this new attribute and value should be added accordingly.

  4. `tags.c` - Now the new attribute will be verified for each tag it is associated with in the `tag_defs[]` table. Like for example the `<button ...>`, `{ TidyTag_BUTTON, ...` has `&TY_(W3CAttrsFor_BUTTON)[0]` assigned.
 
 So, normally, just changing 3 files, `tidyenum.h`, `attrs.c`, and `attrdict.c`, will already adjust `tags.c` to accept a new `attribute=value` for any tag, or all tags. Simple...

 CMake comes in two forms - command line and GUI. Some installations only install one or the other, but sometimes both. The build commands below are only for command line use.
 
 Also the actual build tools vary for each platform. But that is one of the great features of CMake, it can generate various 'native' build files. Running `cmake --help` should list the generators available on that platform. For sure one of the common ones is "Unix Makefiles", which needs autotools make installed, but many other generators are supported.
