We optimize this method by using the GetFileAttributesExA native Windows
API to check for file existence when possible. For real Windows builds
we always use it. For Cygwin we use cygwin_conv_to_win32_path to get a
native Windows path if possible and otherwise fall back to 'access'.

See issue #8826.
When reading the depend.internal file, check only once for every depender
whether it exists, instead of repeatedly in a loop for each dependee. Within
that function it can only change of the depender is removed. This is taken
care of.
This reduces the number of access() calls in kdelibs/khtml from 180000 to
90000 (i.e. 50%), and reduces the time for that (without the actual
scanning) from 0.3 s to 0.21 s on my system.

This subclass of cmGlobalXCodeGenerator only provided two virtual method
overrides, and it made construction of the Xcode generator instance
complicated. This commit removes it and replaces the virtual methods
with tests of the Xcode version. The change removes duplicate code.
Previously we checked for this flag by parsing the version number of GCC
out of 'gcc --version', but this is not reliable because the format can
vary greatly. Now we run 'gcc -v --help' and look for '-isysroot' in
the list of options.
We also now store the result on a per-language basis in the per-compiler
info file "CMake<LANG>Compiler.cmake". This is necessary to make it
accessible from try-compile projects so that they generate correctly.
Some vendor tools convert PDB file names given on the command line to
lower-case before creating the file. When CMake places a mixed-case PDB
file name into the build system, the file does not exist the first time
and it is written with mixed case. After the first build though the
native tool has created a lower-case version of the file. If CMake does
CollapseFullPath again, the file exists so the actual-case lookup gets
the lower-case name. This causes the build files to change so the
project rebuilds.
The solution is to avoid calling CollapseFullPath for files generated by
the build. In the case of PDB files we already construct them from
paths that have been collapsed, so we can just skip the call altogether.
See issue #9350.
In cmMakefile::AddSubDirectory we were checking for addition of the same
source directory multiple times. However, the check code was incorrect
because it compared pointers instetad of pointed-to strings. Since the
check was written, a better check was added right after it to enforce
unique binary directories (in which case duplicate sources are fine).
This commit simply removes the old-style check code.
Before this change all targets were displayed in the top level directory of
the project. Now the targets are displayed in the correct directory.
The targets "clean" and "all" are now created in every subdirectory.
Also now the targets for just compiling one file, preprocessing one file,
assembling one file are are created for Eclipse.
Additionally all targets get a prefix now in eclipse, so that they are
sorted in a way which makes sense (global targets first, then executable and
libraries, then object files, then preprocessed, then assembly). Also
this prefix gives the user a hint what the target is, i.e. whether it's a
library or an executable or something else.

This commit teaches configure_file how to handle directories for input
and output. It is an error if the input is a directory. If the output
is a directory we put the configured copy of the input file in it with
the same name. See issue #9537.
The configure_file() command now converts relative output paths to full
paths using the current binary directory. Input relative paths were
already converted using the current source directory, but this behavior
was not previously documented.
Now gcc is queried also for the builtin definitions, and they are then added
to the .cproject file. This should make the preprocessor highlighting in
eclipse work better (#9272)
Patch mostly from Miguel.

The Intel Visual Fortran compiler plugin for MS Visual Studio may be one
of several versions of the Intel compiler. This commit teaches CMake to
detect the plugin version and set the version number in .vfproj files.
See issue #9169.
This method returns the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\<version>
A protected GetIDEVersion method retrieves the version-specific part of
the key name.
The commit "Improve dynamic variable scope implementation" optimized
function scopes using an efficient parent scope pointer. However, the
parent scope used to initialize a new directory might not exist later
(like add_subdirectory called inside a function of the parent scope).
This caused CMake to crash when following the dangling pointer to the
original parent scope.
We fix the problem in this commit by always computing the closure of the
parent scope at directory initialization time so that no parent scope
pointer is needed. See issue #9538.
The cmProcess::Buffer class derives from std::vector. We were using
local variable 'data' in the GetLine method but this name shadowed a
member of vector with GNU. This renames it to 'text'.
When we clear the buffer for an output pipe after returning the last
partial line (without a newline) we need to set the partial line range
to empty. Otherwise the buffer object is left in an inconsistent state.
