FetchContent redirection of find_package() calls doesn't fully ignore version constraints
When `FetchContent_MakeAvailable()` sets up its `find_package()` redirection in the `CMAKE_FIND_PACKAGE_REDIRECTS_DIR`, all future `find_package()` calls for that dependency MUST accept those files as fulfilling the request, regardless of any version constraints such calls might specify. The automatically generated `<pkgname>-config-version.cmake` file sets `PACKAGE_VERSION_COMPATIBLE` to true so that any `find_package()` call that includes a version constraint won't automatically fail. However, it should also set `PACKAGE_VERSION_EXACT` to true in case `find_package()` calls include the `EXACT` keyword, but this is currently missing. The automatically generated file should be updated to set this variable as well.
Since this is a bug in the logic for a new feature added in CMake 3.24, the fix suggested above should be back ported to the release branch.
