This brings the functionality of `cmake -E create_symlink` and more to scripts.
The default behavior is to create hard links.
The `SYMBOLIC` argument can be used to create symlinks instead.
The `COPY_ON_ERROR` argument enables a fallback to copying the file in case the link fails.
The `RESULT <var>` retrieves the error message generated by the system.
It is set to "0" on success.
Fixes: #16926
The allows `-E create_symlink` to work on Windows. It utilizes
`uv_fs_symlink`. I am still unsure exactly which Windows platforms will
work without requiring Administrator privileges or needing a user/group
with the "Create Symbolic Links" User Rights. It does work with my
Windows 10 Pro with Developer Mode turned on. In the test suite check
that the symlink either worked or failed with a permissions error.
Use recent changes in cmSystemTools::FileExists to check that a symlink
is broken.
The use of `uv_fs_realpath` introduced by commit v3.11.0-rc1~445^2~1
(cmSystemTools: Implement GetRealPath on Windows, 2017-10-02) causes
`subst` drives to be expanded on Windows, breaking existing use cases.
Revert its use until an alternative implementation can be chosen.
Preserve the behavior introduced by commit v3.11.0-rc1~445^2
(cmTimestamp: For symlinks switch to timestamp of resolved path,
2017-10-02) by retaining use of `uv_fs_realpath` in a function of
a different name.

* Change some functions to take `std::string` instead of
`const char*` in the following classes: `cmMakeFile`, `cmake`,
`cmCoreTryCompile`, `cmSystemTools`, `cmState`, `cmLocalGenerator`
and a few others.
* Greatly reduce using of `const char*` overloads for
`cmSystemTools::MakeDirectory` and `cmSystemTools::RelativePath`.
* Remove many redundant `c_str()` conversions throughout the code.

This commit continues the changes made in CTest to support std::chrono
by
applying it throughout every component where a duration was used.
No functional change intended.
Since libuv commit v1.14.1~7 (win: add uv__once_init() calls,
2017-08-30) the libuv initialization of the file translate mode may take
place even if we do not use a uv loop. This change was included in our
libuv update commit f4a26c748b (libuv 2018-01-19). Therefore use of
libuv even through `cmSystemTools::GetRealPath` in any executable may
trigger its file translate mode setting.
Factor out the logic added to `cmake.exe` by commit v3.9.0-rc4~10^2
(cmake: Fix default file translate mode when using libuv, 2017-06-13)
and re-use to initialize all executables.
Issue: #16962
The KWSys `SystemTools::SplitProgramFromArgs` implementation goes into
an infinite loop when the value is just " " (a space). Since the
"program path with unquoted spaces plus command-line arguments"
operation it is trying to provide is poorly defined (string parsing
should not depend on filesystem content), just stop using it.
Instead consider the main two use cases the old approach tried to handle:
* The value is the name or absolute path of a program with no quoting
or escaping, but also no command-line arguments. In this case we
can use the value as given with no parsing, and assume no arguments.
* The value is a command-line string containing the program name/path
plus arguments. In this case we now assume that the command line
is properly quoted or escaped.

The internal tool "cmake_ninja_depends" now supports reading the list of ddi
files from a reponse file to circumvent Windows command line length limits.
Use this response file for dyndep rule on Windows.
Move the logic to cmSystemTools to be shared among the generators.
Revise the implementation and add comments justifying each possible
source for a limit.
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
Add support for natural string order by comparing non-numerical
character directly and numerical number by firstly collecting contiguous
digits. The order is defined by the `strverscmp(3)` manual [1].

Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.
* If you reached this commit for a line in `git blame`, re-run the blame
operation starting at the parent of this commit to see older history
for the content.
* See the parent commit for instructions to rebase a change across this
style transition commit.
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

The OUTPUT_NORMAL value is not really "normal" and has only one caller.
Rename it to OUTPUT_FORWARD to clarify that we are explicitly forwarding
the output.
Extend the RunSingleCommand signature to capture stdout and stderr
separately. Allow both to be captured to the same std::string
to preserve existing behavior. Update all call sites to do this
so that this refactoring does not introduce functional changes.
Add an option to set the mtime of entries in a tarball so that one can
create a tarball with a consistent content hash (e.g. MD5) for a given
set of files regardless of their current timestamps on disk. This will
be useful for submission of tarballs to CDash, which tracks content
hashes to avoid duplication.

Convert the StringToInt helper into a StringToLong helper with a 'long'
result type. This will make the helper more useful to other callers
that want to use strtol.
While at it, also check errno after calling strtol in case the
conversion fails with a range error.
Factor a common callback type out of StdoutCallback. Add an equivalent
StderrCallback. While at it, use "size_t" for the data length instead
of "int".
Teach "ctest --build-and-test" to capture the Stderr callback because
output sent through it is part of the logical CMake process output.
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.
The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
Several CMake operations need to replace files in rapid succession.
This commonly fails on Windows due to filesystem lock behavior so
we have retry loops. No matter how many times we retry or how long
we delay there will inevitably be someone with an environment that
needs more. Make the retry count and delay configurable in the
Windows Registry keys:
{HKCU,HKLM}/Software/Kitware/CMake/Config
in DWORD values
FilesystemRetryCount = Number of tries
FilesystemRetryDelay = Delay in milliseconds between tries
Leave the feature undocumented for now to see how it goes.
Rename cmSystemTools::FindExecutableDirectory to FindCMakeResources.
Teach it to compute the locations of cmake, ctest, cpack, ccmake, and
cmake-gui executables, and the location of CMAKE_ROOT. Provide this
information from static cmSystemTools::Get<resource>() methods.
Refactor code that needs these locations to use the new APIs.
Teach FindCMakeResources to use the OS X system API to lookup the
executable location. When running from the CMake build tree itself,
leave a file in the tree that FindCMakeResources can use to read the
location of the source tree. This avoids the need to compile the source
tree location into a binary that may be installed and used without the
source tree.
Teach the QtDialog on OS X to create a "cmake-gui" symlink in the build
tree next to "cmake" and the other tools, as is already done in the
install tree for the application bundle. This ensures a consistent set
of executables are available in one directory.
Install the Help directory next to Modules to make it available in CMake
distributions. Use cmRST to read Help .rst documents and print them as
help output.
Add options
--help-manual-list
--help-manual
to list available manuals or print one of them. Implement the options
--help-commands
--help-modules
--help-policies
--help-properties
--help-variables
by mapping to the corresponding manual page. Implement the options
--help-command-list
--help-module-list
--help-policy-list
--help-property-list
--help-variable-list
by globbing the available Help .rst documents of the corresponding type
and reading their titles. Implement the options
--help-command
--help-module
--help-policy
--help-property
--help-variable
by globbing the matching Help .rst document(s) and printing them.
Pass the original file handles to the native tool when using the
--use-stderr option in the build command. This enables the
usage of advanced terminal features like colored output.
While calculating dependencies collapse sequences such as
../../../a/b/c/../../d/e/../../e/f
to avoid total path lengths over the Windows path length limit as much
as possible.

8576b3f OS X: Add support for @rpath in export files.
00d71bd Xcode: Add rpath support in Xcode generator.
94e7fef OS X: Add RPATH support for Mac.
RPATH support is activated on targets that have the MACOSX_RPATH
property turned on.
For install time, it is also useful to set INSTALL_RPATH to help
find dependent libraries with an @rpath in their install name.
Also adding detection of rpath conflicts when using frameworks.
Sometimes it wasn't returning an error and one could continue
with the generate generate as if no errors occurred, and even
with an incomplete configure step.
Replace use of AppendEnv/RestoreEnv pairs with instances of
SaveRestoreEnvironment. Simplify the signature of AppendEnv and use it
in place of similar loops elsewhere. Move the RestoreEnv implementation
inside the SaveRestoreEnvironment destructor which is the only place
left that calls it.
Instead of enabling interrupt only when a progress or message callback is called, add a new callback specifically for
interrupt. This new callback is called from GetFatalErrorOccured() so cmake-gui can immediately report interrupt status
instead of calling queuing a call to cmSystemTools::SetFatalErrorOccured() and waiting for the progress or message
callback to be called to process that queued call.

The Sun compiler does not provide the proper vector constructor to
initialize it from an iterator pair of a non-matching type. Extend the
ParseUnixCommandLine API to provide a vector of the proper type so no
conversion is needed.
The naive time(0) seed is unique only within one second. Instead try to
read a real source of entropy and otherwise fall back to a combination
of the process id and high-resolution time.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
