In commit 9c0491a3e4 (cmDyndepCollation: write out scanned source
information too, 2024-03-25) via !9708, the `sf_map` gained a new job of
also being used to track non-file set sources which could import
modules. This was implemented by removing processed `FILE_SET TYPE
CXX_MODULES` sources from the map and working with the sources
remaining. When a `FILE_SET TYPE CXX_MODULES` source appeared multiple
times, this would then erroneously complain that it "was not scheduled
for compilation". Use a set of source paths to track sources that have
already been processed. If duplicates are found, trigger an author
warning and skip the duplicate file.

In commit 0994bc7929 (cmake: Preserve symlinks in references to itself
when possible, 2024-11-11) we stopped looking for resources using the
real path of the directory containing `cmake`. Restore it as a fallback
to support layouts like `/{bin -> usr/bin}/cmake`.

Revert commit 4a11772618 (GenEx: Limit TARGET_PROPERTY transitive
closure optimization to subgraphs, 2024-05-31, v3.31.0-rc1~114^2).
The change caused substantial performance regressions in some
existing use cases. Revert it pending further investigation.
Issue: #25728Fixes: #26457
When profiling Qt builds on macos, about 2.2% of a `cmake` invocation
was spent reading from `/dev/urandom`. Use a (thread)local rng to
mitigate this cost, particularly in `cmGeneratedFileStreamBase::Open`.

Rewrite how cmPackageInfoReader parses "includes" to also support
language-specific includes (i.e. map-of-string-to-list-of-string).
Previously, we only supported the simpler list-of-string shorthand for
"includes" that do not have any language-specific includes.
Rewrite cmPackageInfoReader's parsing of the "definitions" attribute.
The old logic (having been originally adapted from proof-of-concept
parsing code circa 2023) was parsing the attribute according to its
specification as of CPS 0.11, but the representation was changed in
CPS 0.12. Add a test to verify that definitions are being imported
correctly. Remove unnecessary setting and resetting of CMAKE_PREFIX_PATH
in the test.
The `find_package_handle_standard_args(FOUND_VAR)` is deprecated as of
CMake 3.3 and both the `<PackageName>_FOUND` and the upper-cased
`<PACKAGE_NAME>_FOUND` are set with or without using this option.
Additionally, find modules and docs are also synced with this to make it
clearer.
