#pragma once is a widely supported compiler pragma, even though it is
not part of the C++ standard. Many of the issues keeping #pragma once
from being standardized (distributed filesystems, build farms, hard
links, etc.) do not apply to CMake - it is easy to build CMake on a
single machine. CMake also does not install any header files which can
be consumed by other projects (though cmCPluginAPI.h has been
deliberately omitted from this conversion in case anyone is still using
it.) Finally, #pragma once has been required to build CMake since at
least August 2017 (7f29bbe6 enabled server mode unconditionally, which
had been using #pragma once since September 2016 (b13d3e0d)). The fact
that we now require C++11 filters out old compilers, and it is unlikely
that there is a compiler which supports C++11 but does not support
#pragma once.
Provide a standardized way to handle the C++ "standard" headers
customized to be used with current CMake C++ standard constraints.
Offer under directory `cm` headers which can be used as direct
replacements of the standard ones. For example:
#include <cm/string_view>
can be used safely for CMake development in place of the `<string_view>`
standard header.

CPACK_EXT_ENABLE_STAGING enables optional staging
and CPACK_EXT_PACKAGE_SCRIPT allows to specify an optional
script file that can package staged files via an
external packaging tool.
Issue: #18236
This refactoring will allow cmCPackExtGenerator to skip the install
step while still gathering up information about the CPack components
and groups. Besides, this function was too long, and needed to be
broken up anyway.
Introduces CPACK_DEFAULT_DIRECTORY_INSTALL_PERMISSIONS
variable which adds support for functionality introduced
by CMAKE_DEFAULT_DIRECTORY_INSTALL_PERMISSIONS variable.

We now require C++11 support including `override`. Drop use of
the old compatibility macro. Convert references as follows:
git grep -l CM_OVERRIDE -- '*.h' '*.hxx' '*.cxx' |
xargs sed -i 's/CM_OVERRIDE/override/g'
New options is: DEFAULT, VIRTUAL, FORCED_INSTALLATION,
DISPLAY_NAME, DESCRIPTION and RELEASE_DATE.
Options added for both cpack_ifw_configure_component and
cpack_ifw_configure_component_group command.
Apply the change from commit bd3d0eaf (cmCTest: don't redefine cout and
cerr, 2016-09-01) to the rest of ctest and cpack. These definitions
are no longer needed because our conventions are well established.
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.
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.

Teach set_property and get_property an "INSTALL" property type to be
associated with install-tree file paths. Make the properties available
to CPack for use during packaging. Add a "prop_inst" Sphinx domain
object type for documentation of such properties.
Most of these are turned into strings in the body of the method
(multiple times in some cases). Accept strings to simplify the API and
keep string construction down.
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.
More generally add the check for possible generator "activation" at
runtime depending on a generator specific check.
The dynamic behavior is currently implemented only for MacOS
and should be fully backward compatible for other system.

The [usually] wrong usage of absolute DESTINATION in INSTALL rules
keeps popping-up on the ML. We shall have some way to:
1) easily detect it.
2) forbids this for some CPack generator like NSIS
In fact it should certainly be forbidden for *any* generators
when used on Windows but we may implements that on top of the current
patch.
The patch ask the task to the generated cmake_install.cmake scripts.
Those scripts are a little bit more complicated with that but
iff there are absolute DESTINATION. This cost nothing if relative
DESTINATION are used.
Two new vars are introduced (and documented to handle that):
CPACK_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
and
CPACK_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
For example, when CPACK_<GEN>_COMPONENT_INSTALL and
CPACK_MONOLITHIC_INSTALL are both set. Previously, this
combination of variable settings produced an error without
any explanation. Now, in this case CPACK_MONOLITHIC_INSTALL wins
without trouble.
This is useful for when e.g. CPACK_ARCHIVE_COMPONENT_INSTALL is
globally on and one wants MONOLITHIC install for STGZ (but not
other generators). The same behavior may be obtained by re-setting
CPACK_ARCHIVE_COMPONENT_INSTALL to 0 but in any case the
'both set' case should have been handled without error.
Also allow generators to override the default packaging method.
Add a ONE_PER_GROUP option so that method can be specified by the user without relying on defaults.
