Not always, some people sometimes feel like doing it by hand from scratch with if(EXISTS ...). Sadly.

CMAKE_PREFIX_PATH *is* used by find modules.

The find modules use find_* commands, and those use CMAKE_PREFIX_PATH.
See the documentation of find_library, find_path, etc. for details.
Each command searches an appropriate `<prefix>/<dir>` where `<dir>`
is based on the kind of command doing the searching.
