+After a language is enabled, adding sources files with the corresponding extension to your target will automatically use the appropriate compiler/assembler for it.
+
+_Note_: It is generally discouraged to disable the `C` language, unless you are absolutely sure it is not used. Sometimes projects added with `fetch-content` implicitly require it and the error messages can be extremely confusing.
