Brad King 731427a646 cmGlobalGenerator: Do not re-add CMAKE_<LANG>_COMPILER
The cmGlobalGenerator::ResolveLanguageCompiler method, invoked only by
Makefile generators, contains code originally added by commit v2.4.0~796
(..., add new generators for msys and mingw, 2005-12-22) to compute the
full path to the compiler and save the result back into the cache value.
Since then the CMakeDetermine*Compiler modules have learned to resolve
the full path to the compiler and save it in CMake*Compiler.cmake files
configured in the build tree.  The value of CMAKE_<LANG>_COMPILER in the
cache is now only for reference of what the user originally specified.
The full path is now available in a normal variable of the same name,
and this is used by project code and the generators.

When the user specifies -DCMAKE_<LANG>_COMPILER=name on the command-line
of an existing build tree that uses a Makefile generator, it is first
stored in the cache with an uninitialized type.  Then later when
ResolveLanguageCompiler updates the cache entry and sets the type to
FILEPATH, cmMakefile::AddCacheDefinition does CollapseFullPath on the
"name" and ends up with something like "$PWD/name" which is unlikely to
be correct.  Furthermore, cmMakefile::AddCacheDefinition proceeds to
remove the normal variable of the same name, so the value originally
saved in CMake<LANG>Compiler.cmake is ignored and the generators use the
wrong path to the compiler.

Resolve this by dropping the code from ResolveLanguageCompiler that
touches the cache value of CMAKE_<LANG>_COMPILER.  As explained above it
is no longer needed anyway.

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 and supported by `Kitware`_ 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.

.. _`CMake Users List`: http://www.cmake.org/mailman/listinfo/cmake

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
