Distro maintainers who are building from Git with patches added on
may want to disable the automatic Git suffixing, as it does not
provide any useful information and simply confuses the end user.
Add an undocumented CMake_VERSION_NO_GIT variable to disable this.
Update the approach from commit fe2c558ba6 (CMakeVersion: Preserve Git
information during 'git archive', 2019-07-25, v3.16.0-rc1~337^2) to
prefer `export-subst` information. This will allow exported source
trees to be imported into unrelated Git repositories while still using
the original upstream CMake commit information.
While the flag tables for C and C++ were generated from MSBuild `.xml`
files, the CSharp flag tables were written by hand. Copy the `v141`
flag table to use for the `v142` toolset.
Remove the special case added by commit 626c51f47b (VS: Update for
Visual Studio 2019 Preview 2, 2019-01-24, v3.14.0-rc1~74^2) that mapped
the v142 flag table lookup to v141 since we now have the real v142
table.
Fixes: #19828
The OLD behaviors of all policies are deprecated, but only by
documentation. Add an explicit deprecation diagnostic for policies
introduced in CMake 3.9 and below to encourage projects to port away
from setting policies to OLD.
Other multi-word command line options use hyphens to separate
the words, so the --loglevel option introduced in CMake 3.15 was
inconsistent in this regard. Rename it to --log-level but still support
the original --loglevel name to preserve backward compatibility.
* Added a fairly comprehensive test suite
* Separated the graph traversal logic from the Graphviz generation
code by introducing a new class, cmLinkItemsGraphVisitor{.h,cxx}
* Made the graph traversal logic less ad-hoc by using existing
methods in the GlobalGenerator; this fixed a few bugs
* Added support for new target types: custom targets, object
and unknown libraries
* Improved support for ALIAS libraries by showing the alias(es)
in the graph
* Introduced new flags to control those new libraries (consistent
with existing flags)
* Updated the documentation
* Removed useless setting to set graph type in dot file
* Improved the node/edge shapes (nicer, more consistent)
* Added a legend to the graph
* Some refactoring and cleanup of the Graphviz generation code
* Added test and fix for issue 19746
Extend the fix from commit 0578239d3a (VS: Tell VS 16.4 not to verify
SYMBOLIC custom command outputs, 2019-09-23, v3.15.4~2^2) to apply to
outputs in CMake-provided targets like `install`. Simply mark these
outputs as `SYMBOLIC` too since they are not actually generated.

Since commit b80557c7bd (file(GENERATE): Evaluate early to allow
generating source files, 2014-11-04, v3.2.0-rc1~398^2) we create the
`cmSourceFile` instances marked with a `GENERATED` source file property
before tracing source dependencies. Move it to even earlier so that
steps in `cmGlobalGenerator::AddAutomaticSources` can operate on all
sources. This also avoids the accidental `O(n^2)` calls for `n` local
generators that we had previously.
This is also needed since commit 83c1657ff7 (Unity build: Generate
sources during Compute step, 2019-10-03) to support `file(GENERATE)`
outputs as sources in a target with `UNITY_BUILD` enabled.
The relative path check added by commit 5838aba1aa (Export: Report error
on relative include with genex., 2013-11-26, v3.0.0-rc1~285^2) was added
one condition too early. If the value starts in `${_IMPORT_PREFIX}`
(which comes from `$<INSTALL_PREFIX>`) then it is an absolute path.
Fixes: #19791
If the target has C files, it will get a C PCH file.
The same for C++ files. The linker language is no
longer used to determine which language to use for
PCH.
Fixes: #19790
The unity build sources need to be added for all generators. Create
them during `cmGlobalGenerator::Compute` to avoid duplicating the calls
in every generator. We already handle Qt autogen there too.
