Brad King 86578eccf2 Simplify CMake per-source license notices
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names and years are hard to maintain and often out-of-date or plain wrong.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.

Tobias Hunger b13d3e0d0b cmake-server: Bare-bones server implementation
Adds a bare-bones cmake-server implementation and makes it possible
to start that with "cmake -E server".

Communication happens via stdin/stdout for now.

Protocol is based on Json objects surrounded by magic strings
("[== CMake Server ==[" and "]== CMake Server ==]"), which simplifies
Json parsing significantly.

This patch also defines an interface used to implement different
versions of the protocol spoken by the server, but does not include
any protocol implementaiton.

Brad King 9a53af4068 Do not build libuv on Cygwin
Currently libuv does not support Cygwin (see libuv issue 832)

Take logic from upstream `Makefile.am` and `configure.ac` to build libuv
sources.

Update `uv.h` to include KWSys Large File Support configuration so that
consistent stream libraries are used (on AIX with XL).

Add a `cm_uv.h` header to include the CMake-provided copy of the `uv.h`
header from CMake sources.

Brad King 9ad10c8feb cmake-gui: Reference LGPLv3 when redistributing Qt
Download http://www.gnu.org/licenses/lgpl.txt and place it as
Licenses/LGPLv3.txt in our source tree.  When building cmake-gui, use
option CMake_GUI_DISTRIBUTE_WITH_Qt_LGPL to enable notification in the
"About" dialog of how the distribution of Qt is licensed.  Install the
license file as ${CMAKE_ROOT}/Licenses/LGPLv3.txt so that the dialog can
display a path to it.

Brad King 190a5fdffd Automatically use OpenSSL by default on Linux and FreeBSD if available
Since https is almost ubiquitous nowadays we should support it by
default whenever possible.  When building our own curl, we already
automatically enable SSL/TLS support on Windows and OS X by using the
OS-native APIs.  On UNIX platforms we need to use OpenSSL but have not
done so by default before, leading to possible user confusion when https
transfers fail later.  Fix this by searching for OpenSSL quietly and
enabling use of it automatically if it is found.

Do this only on Linux and FreeBSD for now because on other UNIX
platforms (e.g. AIX, HP-UX, SunOS) it seems too easy to find an
OpenSSL that is not compatible with the target compiler.

Raphael Kubo da Costa ffa6f057b4 Avoid using C11 to build CMake if _Thread_local support is broken
Support for C11's _Thread_local was introduced in GCC in the 4.9 series,
even though we make the C11 compiler flags available in CMake with GCC
>= 4.6.

FreeBSD's runetype.h uses _Thread_local, which causes CMake's own build
to fail when using GCC < 4.9 and -std=gnu11:

  /usr/include/runetype.h:92:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'const'
   extern _Thread_local const _RuneLocale *_ThreadRuneLocale;

Add a test for _Thread_local support and only build CMake itself with
C11 support if it works.

Brad King 26f5445bb4 Do not install 3rd-party dependencies by default
Disable the CMake_INSTALL_DEPENDENCIES option by default and turn it on
explicitly in our packaging scripts.  This simplifies packaging in
distributions that provide the dependencies for us without having to
install them.  We only need 3rd-party runtime dependencies to be
installed for packaging with redistributable binaries.

Brad King 3307e10fc4 Avoid using C++14 to build CMake if cstdio breaks
The GNU 4.8 standard library's cstdio header is not aware that C++14
honors C11's removal of "gets" from stdio.h and results in an error:

  /.../include/c++/4.8/cstdio:120:11: error: no member named 'gets' in the global namespace

Detect this problematic case and default to using C++11 instead of
C++14 for building CMake itself.

Brad King a576844263 FindJsonCpp: Drop new module due to upstream jsoncpp providing package
Since jsoncpp 0.7.0 (2014-11-20) the upstream may provide a CMake
package configuration file such that find_package(jsoncpp) will find a
jsoncppConfig.cmake file.  In order to avoid conflicting with this
(especially on case-insensitive filesystems), and since we always prefer
projects to provide package config files (that they maintain), it is
better to not provide FindJsonCpp publicly.

Move FindJsonCpp into a private source directory that is not installed
so that we can still use it for building CMake itself.

Clinton Stimpson cdc29c3608 Encoding: Switch to use UTF-8 internally by default on Windows.
This fixes several reported bugs about CMake not handling
non-ascii paths on Windows.

Practically, the use of some unicode characters may still
be limited by the build or compiler tools.

For example, a user may be limited by the build tools to
using characters within the Windows ANSI code page (which can
include non-ascii characters in the current system language).

Stephen Kelly d49f1c5e94 Build CMake with most-recent available language dialect.
When CMake is built with CMake 3.1 or later, appropriate -std=
options will be added for GNU and Clang compilers while building
C and CXX code.

This allows taking advantage of 'hidden' language features such
as move-constructors, and allows the standard library to enable
the use of more-advanced features too, where available.

This does not change CMake host compiler requirements.

Change the curl library name to 'cmcurl'.  Disable blocks of code within
curl CMakeLists.txt files that we do not need for CMake, but leave the
code in place to make merging with curl updates easier.

The CMake_TEST_EXTERNAL_CMAKE option added by commit 9608ef6f (Tests:
Optionally configure tests exclusively, 2014-03-03) is intended to allow
one to run the CMake test suite with a compiler that may not be
supported for hosting the build of CMake itself.  However, we currently
use the CMake test infrastructure to test KWIML everywhere that CMake
supports.  In order to continue testing KWIML even in places that CMake
itself does not build, include it even when testing an external CMake.
