Since commit 302a645d73 (CPack/DEB: use `triggers` instead of legacy
postXXX scripts for `ldconfig`, 2026-03-05, v4.4.0-rc1~583^2) the
`triggers` feature refers to `DPKG_EXECUTABLE` if the latter is defined.
Unfortunately, it is defined only if one particular execution branch has
executed. Move the `find_program(dpkg)` to the function scope to make
it available in all execution branches.
Commit 5abaf65154 (Check*: Restore toleration of `;-W...` in
CMAKE_REQUIRED_FLAGS, 2026-06-24, v4.4.0-rc3~2^2) introduced logic to
prevent `-W*` arguments in `CMAKE_REQUIRED_FLAGS` from being passed as
CMake arguments. It was never the intent of `CMAKE_REQUIRED_FLAGS` to
support such usage; however, since older versions of CMake would
silently accept such arguments, some users were unintentionally passing
compiler warnings as CMake arguments. Although this usage is incorrect,
it was silently tolerated until CMake 4.4, which began treating unknown
`-W*` as an error.
Because it turns out that modules besides `CheckSource{Compiles,Runs}`
are affected, we are going to need the logic added by that commit in
many more places. As a first step toward accommodating that need, move
the logic to a new internal helper. While we're at it, try to generally
consolidate the common logic for handling the various variables that the
`Check*` family of modules uses for injecting arguments into the
ultimate `try_compile` calls.
The `CMAKE_REQUIRED_FLAGS` variable, used by the various entry points to
`cmake_check_source_{compiles,runs}`, specifies that flags shall not be
separated by semicolons. This is because the way in which it is passed
to the child `cmake` process means that, when considered as a list (with
semicolon separated items), only the first item is actually used as
compile flags, with any additional items actually seen as arguments to
the child `cmake` process. While this usage is unsupported, if invoked
accidentally, flags starting with `-W` were silently ignored by CMake.
However, CMake 4.4 newly complains about unrecognized warning
categories, which means that uses which were silently broken now result
in a hard error.
In the longer term, it would be helpful to introduce a policy to repair
improper use of semicolons in `CMAKE_REQUIRED_FLAGS` in order to do what
the user probably meant. However, for various reasons, we do not want to
introduce a policy to CMake 4.4 at this time, and anyway, the policy
won't help users that haven't enabled it. Therefore, alter the 'check
source' functions to detect arguments being passed to `cmake` rather
than the compiler, and remove any such that start with `-W`. This
removes any arguments that newly cause errors starting with CMake 4.4,
while not otherwise altering behavior in case any users were abusing
this implementation quirk.
Strictly speaking, this means that users can no longer abuse this quirk
to alter CMake's diagnostics. However, the only case in which this
should be observable is if the user is already abusing the quirk to
inject their own CMake logic into the CMake-provided test projects.
Since this was never supported, anyone doing that can keep the pieces.

Capture `execute_process` calls' `RESULT_VARIABLE`.
We don't actually need to check the result as we presume the existing
logic is already adequate, and sometimes programs return non-zero values
as result of valid query. I.e. this is a "safe" way to broadly protect
these scripts.

The Pelles C compiler does not support ASM, and the `poasm` assembler
uses a distinct syntax. Add a dedicated language as we do for similar
cases from other vendors. Leave documentation commented out for now
because the PellesC toolchain support in general is not yet documented.

According to [this] commit message in the `rpmlint` codebase,
a %clean section is not necessary since `rpm` 4.8.0 (2010)
and nowadays `rpmlint` at least issues a warning about it, and
(seems) in some distros it's even considered as an error.

Ask `stat` to output only human-readable permissions and nothing else.
Secondly, simplify parsing algorithm. Instead of multiple regex matches
transform permissions into a list and split into groups.
On windows when you run `nvcc -v` all the env variables will
be printed before nvcc verbose output. This allows us to handle
the cases where env variable exists with the same name as a magic
nvcc keyword we parse
Previously, `CMAKE_<LANG>_LINK_FLAGS` was an undocumented variable used
for linking executables only. Re-spell that variable mirroring the
existing spellings for shared and module libraries, and add policy
CMP0210 to preserve compatibility.
Then, repurpose `CMAKE_<LANG>_LINK_FLAGS` to provide a variable to be
used for per-language link flags for all target types, along with a
per-configuration variant. These are added to the `<LINK_FLAGS>` rule
placeholder in the generators.

Add a new variable `CPACK_DEBIAN_COMPRESSION_LEVEL` to control the compression
level used when generating Debian packages. This complements the existing
`CPACK_DEBIAN_COMPRESSION_TYPE` variable and allows finer control over the
compression performance vs. size trade-off. Supported values correspond to
the compression level accepted by the underlying compressor (e.g. gzip, xz,
zstd, etc.).
By setting CPACK_WIX_CAB_PER_COMPONENT users can generate one
.cab per component instead of one .cab per installer.
WiX compresses .cab files in parallel.
This may potentially speed up installer creation.
May also allow larger installers (there is a 2GB per .cab limit).
