Historically CMake used three version components for the feature level.
We released new features while incrementing only the third version
component.  Since commit v2.8.2~105^2~4 (New version scheme to support
branchy workflow, 2010-04-23) we used the fourth version component for
bug-fix releases and the development date:

 <major>.<minor>.<patch>[.<tweak>][-rc<n>] = Release
 <major>.<minor>.<patch>.<date>[-<id>]     = Development

This solidified use of three components for the feature level, and was
necessary to continue releasing 2.x versions because:

* Some existing projects performed floating-point comparisons of
  ${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION} to 2.x numbers
  so ``x`` could never be higher than 9.

* Version 2.9.<date> was used briefly in post-2.8.0 development in
  CVS prior to the transition to Git, so using it in releases may
  have caused confusion.

Now that we are moving to 3.x versions, these two restrictions go away.
Therefore we now change to use only two components for the feature
level and use the scheme:

 <major>.<minor>.<patch>[-rc<n>] = Release
 <major>.<minor>.<date>[-<id>]   = Development

Introduction
============

CMake is a cross-platform, open-source build system generator.
For full documentation visit the `CMake Home Page`_ and the
`CMake Documentation Page`_.

.. _`CMake Home Page`: http://www.cmake.org
.. _`CMake Documentation Page`: http://www.cmake.org/cmake/help/documentation.html

CMake is maintained by `Kitware, Inc.`_ and developed in
collaboration with a productive community of contributors.

Building CMake
==============

Supported Platforms
-------------------

MS Windows, Mac OS X, Linux, FreeBSD, Solaris, HP-UX, IRIX, BeOS, QNX

Other UNIX-like operating systems may work too out of the box, if not
it should not be a major problem to port CMake to this platform.
Subscribe and post to the `CMake Users List`_ to ask if others have
had experience with the platform.

Building CMake from Scratch
---------------------------

UNIX/Mac OSX/MinGW/MSYS/Cygwin
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You need to have a compiler and a make installed.
Run the ``bootstrap`` script you find the in the source directory of CMake.
You can use the ``--help`` option to see the supported options.
You may use the ``--prefix=<install_prefix>`` option to specify a custom
installation directory for CMake. You can run the ``bootstrap`` script from
within the CMake source directory or any other build directory of your
choice. Once this has finished successfully, run ``make`` and
``make install``.  In summary::

 $ ./bootstrap && make && make install

Windows
^^^^^^^

You need to download and install a binary release of CMake in order to build
CMake.  You can get these releases from the `CMake Download Page`_ .  Then
proceed with the instructions below.

.. _`CMake Download Page`: http://www.cmake.org/cmake/resources/software.html

Building CMake with CMake
-------------------------

You can build CMake as any other project with a CMake-based build system:
run the installed CMake on the sources of this CMake with your preferred
options and generators. Then build it and install it.
For instructions how to do this, see documentation on `Running CMake`_.

.. _`Running CMake`: http://www.cmake.org/cmake/help/runningcmake.html
