Re-organize the "Binary Targets" section of the manual to have a
dedicated subsection for each kind of binary target. Initialize each
subsection by documenting the object file and link semantics of the
corresponding target type.
Update find_package documentation to describe (the current state of)
support for Common Package Specification packages. Make some general
improvements to the same while we're at it. Add documentation blurb for
the experimental flag that enables CPS support.
Teach find_package to search CPS search paths, and to look for CPS file
names. Modify the set of file names to also include the file type (CPS
or CMake-script). Modify the search function to allow specifying which
file type(s) to consider.
During full path search, each possible path is searched for only one of
the two possible file types. However, subsequent runs, or when
considering a user-specified path (<name>_DIR), CMake will look for both
file types.
Note that this only adds the new path search logic as described above;
CMake does not yet know how to read CPS files, and there is a high
likelihood that Bad Things will happen if it tries. However, this seemed
like a good place to checkpoint.

Add cmAnyDirectoryListGenerator, which matches any directory but also
sorts matches in the same manner as cmProjectDirectoryListGenerator.
Modify SearchFrameworkPrefix to use this, in combination with a literal
path (cmAppendPathSegmentGenerator), instead of cmFileListGeneratorGlob
(which is removed, as it is no longer used). This improves the
consistency of when sorting is available.
This uses cmDirectoryListGenerator's new ability to match anything, as
mentioned in the previous commit.
The `BUILD_TESTING` variable is referenced in `add_test` and
`enable_testing`. It should be documented as it controls the
behavior tests working when projects use `include(CTest)`.
Add documentation to clarify that `find_package` searches paths in the
specified order and stops at the first match. Clarify documentation of
`CMAKE_FIND_PACKAGE_SORT_*` to match the actual behavior.
Note that no behavior is actually changed, this merely improves the
documentation to reflect actual behavior rather than seeming to imply
something else.
Also, update the test to verify that what we claim in the updated
documentation is what's actually happening.
Re-introduce the behavior originally introduced in CMake 3.30.3 by
commit c1ece78d11 (project: non cache <project> prefix variables are
also created, 2024-08-27, v3.30.3~2^2), but this time with a policy for
compatibility.

fa07ddfebf project: Only check non-cache vars when setting project vars
Acked-by: Kitware Robot <kwrobot@kitware.com>

The change in commit 86ad7cc886 (project: Only define non-cache vars if
already defined, 2024-09-15, v3.30.4~2^2) was meant to only check for
non-cache variables when deciding whether to set non-cache project
variables for the current call. However, it erroneously checked for any
variable, including cache variables. This gives the intended result on
the first run, but on subsequent runs a cache variable will exist that
did not on the first run, leading to different behavior between the two
runs. Fix the logic to only check for a pre-existing non-cache
variable, as was originally intended.
Fixes: #26355

Traditionally CMake generates link lines by starting with the direct
link dependencies specified by `LINK_LIBRARIES` in their original order
and then appending indirect dependencies that the direct dependencies
do not express. This gives projects control over ordering among
independent entries, which can be important when intermixing flags
and libraries, or when multiple libraries provide the same symbol.
However, it may also result in inefficient link lines.
Add support for an alternative strategy that can reorder direct link
dependencies to produce more efficient link lines. This is useful
for projects that cannot easily specify their targets' direct
dependencies in an order that satisfies indirect dependencies.
Add a `CMAKE_LINK_LIBRARIES_STRATEGY` variable and corresponding
`LINK_LIBRARIES_STRATEGY` target property to select a strategy.

In c1ece78d11 (project: non cache <project> prefix variables are
also created, 2024-08-27), we started explicitly setting the non-cache
variable for <projectName>_SOURCE_DIR, <projectName>_BINARY_DIR,
and <projectName>_IS_TOP_LEVEL in addition to setting them as
cache variables. This changed the behavior when a project name
was used more than once, and the second project call happens in
the same scope or a child scope of the first. Previously, the first
project call would set cache variables, and the second project call
would not overwrite those cache variables. With the change in
c1ece78d11, after the second project call the non-cache variables
would mask the cache variables and the project code would see
a different value to what it did before.
Setting the non-cache variable was added to handle the case where
a call to FetchContent_MakeAvailable() would set some non-cache
variables, and it just so happened those matched the same cache
variables that the project() command would set in the project being
fetched. The fetched project would then see a different set of
project-specific variables compared to when it was built standalone.
This commit here narrows the change from c1ece78d11 such that
the non-cache variable is only set by project() if there was already
a non-cache variable set. This still fixes the motivating problem
c1ece78d11 was intended to solve, but it avoids changing the variable
values seen by a project that re-uses the same project name in related scopes.

The file generated by install(EXPORT) computes _IMPORT_PREFIX
in a way that assumes a normalized path. If the DESTINATION
contains any ../ components, the computed _IMPORT_PREFIX
would be wrong. Force the DESTINATION path to be normalized,
subject to the new CMP0176 policy.
Also normalize all other DESTINATION paths for consistency,
except for INCLUDES DESTINATION, which is not strictly a
destination but rather a search path to add.

Windows is heading toward making UTF-8 the preferred MBCS. As CMake's
internal encoding, `UTF-8` is effectively equivalent to `NONE`, which
was CMake's behavior prior to 3.15's accidental change to `AUTO`.
Behavior of `ENCODING UTF-8` is independent of CMake's internal
encoding, making it in principle a better default than `NONE`.
Add policy CMP0176 for compatibility and to document the default's
history.
Fixes: #26262
The default was originally AUTO in commit 2ed473b3b8 (execute_process:
Add ENCODING option for Windows child process output, 2016-11-23,
v3.8.0-rc1~232^2) but was changed back to NONE by commit 07c3380a6e
(execute_process: Restore no-decoding default behavior, 2017-02-13,
v3.8.0-rc2~26^2) for CMake 3.8. Later it was accidentally changed back
to AUTO by commit b783e62533 (cmExecuteProcessCommand: Port to
cmArgumentParser, 2019-03-25, v3.15.0-rc1~270^2) in CMake 3.15 but the
documentation was not updated. Document the current default, AUTO, and
add a test case to verify it.

If a single-value keyword is followed by an empty string, the
command unsets the variable for that keyword instead of setting
it to the empty string. This is inconsistent and unexpected. Add
policy CMP0174 which ensures the variable for a single-value
keyword is always set when any value is given, not just for a
non-empty value.
The new CMP0174 policy only affects the PARSE_ARGV form of
cmake_parse_arguments. The older form silently drops all empty
string arguments before processing the argument list.
Fixes: #25972

signature. Describe it explicitly as we do for other conditions that

Add initial support for exporting (install only, for now) Common Package
Specification (https://cps-org.github.io/cps/) format package
descriptions. This has some limitations, such as not supporting
generator expressions (as these cannot be portably exported), and only
partially supporting transitive dependencies, but should be usable for
at least some simple cases. (Actually, $<LINK_ONLY> is theoretically
supportable, but is not yet implemented.)
This still needs tests; these will be added in the next commit. Other
potential improvements include support for language-specific compile
definitions and inferring some package properties from project
properties. Additionally, there is no module support yet; this is partly
pending on having a tool agnostic format for providing the necessary
information.
The document's intro claims that the options documented up top are
the ones common to multiple signatures, but `RENAME` is only valid
for `install(FILES ...)`. Move it to that section of the docs.
* Wraps the llpkgc parser with cmPkgConfigParser
* Adds various resolution and mangling code under cmPkgConfigResolver
* Documents new command cmake_pkg_config(EXTRACT). Documentation is written with
the assumption additional subcommands will be added soon.
* Adds various tests for the above
By specifying CODEGEN as an argument to add_custom_command the
custom command will be added to a codegen build target.
The intent is to provide a convenient way for users to get
their generated files without having to build the whole project.
This can be helpful for code analysis tools which can be useful
for IDEs and CI.
This patch improves the wording of the documentation of the
EXCLUDE_FROM_ALL directory property, and makes the
add_subdirectory()- and fetchcontent-documentation refer to it.
