Subject: [PATCH] [vcpkg.cmake] Setup CMAKE_PROGRAM_PATH for the host if
 possible (#23322)

* Use host tools by default.

* use GLOB_RECURSE and filter the result

* be positiv ;)

* give me debug output

* Revert "give me debug output"

This reverts commit 17737bceda8ed0dbe1a60c2fd831a55e53707dcd.
