In commit a90d2a9eed (IntelLLVM: Add support for Intel LLVM-based
compilers, 2020-11-02, v3.20.0-rc1~89^2~20) we added a `set()` that is
immediately followed by another `set()` of the same variable. Remove
the former.
Fixes: #27019
Remove literal text "subcommand" from error messages. This addresses the
other use of this and improves consistency (see preceding commit). Also,
omit some unnecessary articles, which also improves consistency.
Remove literal text "subcommand" from error messages. Most other
commands report errors like "<command> <subcommand> <message>", where
the message does not include the literal text "subcommand". The `export`
command was one of two exceptions to this.
CMake already says if it's using a system-installed component when
configuring:
-- Using system-installed BZIP2
For clarity, also list what components are using the bundled source
code. Example output:
-- Using system installed: ZLIB
-- Using bundled: BZIP2 CPPDAP CURL EXPAT FORM JSONCPP LIBARCHIVE
LIBLZMA LIBRHASH LIBUV NGHTTP2 ZSTD KWIML
This is useful when verifying packaging of CMake itself.
While I'm unsure about why `cmPackageInfoArguments` was originally
written the way it was, in its current form, the way command sub-parsers
work, the parser never considers arguments associated with a sub-parser
if the sub-parser keyword isn't present. This means that the arguments
associated with `cmPackageInfoArguments` are treated as unknown, and the
logic to reject them being set if `PACKAGE_INFO` is not present can
never actually execute. Therefore, remove it, and remove the associated
(and effectively useless) `enable` argument to its `Check` method.
Instead, ensure that the package name is actually specified. The only
case in which the parser will create the `optional` associated with the
sub-parser arguments is if the relevant keyword (i.e. `PACKAGE_INFO`) is
present. However, while the associated value is `NonEmpty`, the way we
are using the parser does not actually enforce this, and it looks like a
correct fix may be a breaking change. Therefore, enforce it manually for
now.
Add version validation to cmExportPackageInfoGenerator. Specifically, if
a package uses the "simple" version schema (which is the default if no
schema is specified), validate that the specified version actually
conforms to the schema and issue an error if it does not. Also, issue a
warning if the schema is not recognized.
Export generators sometimes need to issue errors, and we had an existing
API for that. However, in the future, it will be useful to issue
non-fatal diagnostics as well. Rework the API to allow specifying the
type of diagnostic to issue.
Introduce an index from source file to source group in
`cmLocalGenerator` to make lookups significantly more efficient
during the source group generation, which could be particularly
slow when dealing with thousands of source files.
Falls back to the recursive lookup when the source file is not present
on the index, which is more likely to happen when dealing with
regex-based sources.

exit, 2025-05-23, v4.1.0-rc1~114^2) to cover termination by Ctrl-C.
