In ‘core-updates’ it’s now possible to specify file patterns, so we
could look for *.cmake files under lib/cmake or share/cmake like this:
(search-path-specification
(variable "CMAKE_MODULE_PATH")
(files '("lib/cmake" "share/cmake"))
(file-type 'regular)
(file-pattern "\\.cmake$"))
Would it help? What else is needed?
