Kulla Christoph 048d1adb4e add_custom_command: Add DEPFILE option for Ninja
Provide a way for custom commands to inform the ninja build tool about
their implicit dependencies.  For now simply make use of the option an
error on other generators.

Closes: #15479

Brad King 0278989405 Ninja: Add `$subdir/{test,install,package}` targets
With the Makefile generator one can use `cd $subdir; make install` to build and
install targets associated with a given subdirectory.  This is not possible to
do with the Ninja generator since there is only one `build.ninja` file at the
top of the build tree.  However, we can approximate it by allowing one to run
`ninja $subdir/install` at the top of the tree to build the targets in the
corresponding subdirectory and install them.

This also makes sense for `test`, `package`, and other GLOBAL_TARGET targets.
It was already done for `all` by commit v3.6.0-rc1~240^2~2 (Ninja: Add
`$subdir/all` targets, 2016-03-11).

Brad King a88c99f1bc Ninja: Simplify computation of GLOBAL_TARGET outputs
In cmGlobalNinjaGenerator::AppendTargetOutputs we previously
handled GLOBAL_TARGET outputs specially in order to avoid adding
directory components to the output.  However, this is not necessary
because cmNinjaTargetGenerator::New already filters out copies of
these targets that are not at the top level.  Instead we can simply
follow the same output computation code path as UTILITY targets.

Brad King e555480c60 Ninja: Fix response file format for GNU-like Clang on Windows
The `CMAKE_<LANG>_SIMULATE_ID` variables are not set to "GNU" for a
GNU-like Clang compiler on Windows.  They are only set to "MSVC" for a
MSVC-like Clang.  Revise our response file format selection accordingly.

Brad King 1296a0eada Ninja: Fix inter-target order-only dependencies of custom commands
Custom command dependencies are followed for each target's source files
and add their transitive closure to the corresponding target.  This
means that when a custom command in one target has a dependency on a
custom command in another target, both will appear in the dependent
target's sources.  For the Makefile, VS IDE, and Xcode generators this
is not a problem because each target gets its own independent build
system that is evaluated in target dependency order.  By the time the
dependent target is built the custom command that belongs to one of its
dependencies will already have been brought up to date.

For the Ninja generator we need to generate a monolithic build system
covering all targets so we can have only one copy of a custom command.
This means that we need to reconcile the target-level ordering
dependencies from its appearance in multiple targets to include only the
least-dependent common set.  This is done by computing the set
intersection of the dependencies of all the targets containing a custom
command.  However, we previously included only the direct dependencies
so any target-level dependency not directly added to all targets into
which a custom command propagates was discarded.

Fix this by computing the transitive closure of dependencies for each
target and then intersecting those sets.  That will get the common set
of dependencies.  Also add a test to cover a case in which the
incorrectly dropped target ordering dependencies would fail.

Brad King 64b5520346 Isolate formatted streaming blocks with clang-format off/on
The clang-format tool can do a good job formatting most code, but
well-organized streaming blocks are best left manually formatted.

Find blocks of the form

    os <<
      "...\n"
      "...\n"
      ;

using the command

    $ git ls-files -z -- Source |
      egrep -v -z '^Source/kwsys/' |
      xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \
        '<<[^\n]*\n(^ *("[^\n]*("|<<|;)$|;)\n){2,}'

Find blocks of the form

    os << "...\n"
       << "...\n"
       << "...\n";

using the command

    $ git ls-files -z -- Source |
      egrep -v -z '^Source/kwsys/' |
      xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \
        '<<[^\n]*\n(^ *<<[^\n]*(\\n"|<<|;)$\n){2,}'

Surround such blocks with the pair

    /* clang-format off */
    ...
    /* clang-format on */

in order to protect them from update by clang-format.  Use the C-style
`/*...*/` comments instead of C++-style `//...` comments in order to
prevent them from ever being swallowed by re-formatting of surrounding
comments.

Brad King e1c7747253 Format include directive blocks and ordering with clang-format
Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first).  First
run `clang-format` with the config file:

    ---
    SortIncludes: false
    ...

Commit the result temporarily.  Then run `clang-format` again with:

    ---
    SortIncludes: true
    IncludeCategories:
      - Regex:    'sys/types.h'
        Priority: -1
    ...

Commit the result temporarily.  Start a new branch and cherry-pick the
second commit.  Manually resolve conflicts to preserve indentation of
re-ordered includes.  This cleans up the include ordering without
changing any other style.

Use the following command to run `clang-format`:

    $ git ls-files -z -- \
        '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
      egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
      egrep -z -v '^Source/cm_sha2' |
      egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
      egrep -z -v '^Utilities/(KW|cm).*/' |
      egrep -z -v '^Tests/Module/GenerateExportHeader' |
      egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
      xargs -0 clang-format -i

This selects source files that do not come from a third-party.

Brad King 6e2a4087f2 Ninja: Centralize path conversion in global generator (#15757)
In the Ninja generator we run all build rules from the top of the build
tree rather than changing into each subdirectory.  Therefore we convert
all paths relative to the HOME_OUTPUT directory.  However, the Convert
method on cmLocalGenerator restricts relative path conversions to avoid
leaving the build tree with a "../" sequence.  Therefore conversions
performed for "subdirectories" that are outside the top of the build
tree always use full paths while conversions performed for
subdirectories that are inside the top of the build tree may use
relative paths to refer to the same files.

Since Ninja always runs rules from the top of the build tree we should
convert them using only the top-level cmLocalGenerator in order to
remain consistent.  Also extend the test suite with a case that fails
without this fix.
