Mark Mossberg 588c6577dd cmake: Clarify comment around exported cmake script ...

The `export()` command purely exports a cmake script into the build
directory; it is not related to find_package at all. It is technically
not necessary. The main use case would be a user copying it into their
internal cmake/ dir in their project, and then using `include()`'ing
that file in their cmake.

The `install(EXPORT...` command is what actually generates a cmake
module that is put on the filesystem in a location that can be found by
`find_package` when in config mode.
