How to use find_package with a user provided Find* module?

[higaski]

I'm trying to download a project which does not contain a CMake configuration from GitHub using

cpmaddpackage(
  NAME
  CWPack
  GITHUB_REPOSITORY
  "clwi/CWPack"
  GIT_TAG
  1.4
  SYSTEM
  YES
  DOWNLOAD_ONLY
  YES)

and then provide my own Find* module by adding a FindCWPack.cmake file inside a cmake subdirectory.

However, trying to call find_package to find this file does not work.

list(APPEND CMAKE_MODULE_PATH ${CMAKE_CURRENT_LIST_DIR}/cmake)

find_package(CWPack)

At least not without also setting CPM_DONT_UPDATE_MODULE_PATH.

Is this intended behavior? I think it is a bit confusing, specially if DOWNLOAD_ONLY is specified as well?
