In find-package mode, cmake executes Modules/CMakeFindPackage.cmake,
which calls find_package(), and this is then evaluated in cmake.cxx,
which prints an appropriate message to stdout, so it can be used
e.g. in a normal Makefile:
$ /opt/cmake-HEAD/bin/cmake --find-package -DNAME=JPEG
-DCOMPILER_ID=GNU -DLANGUAGE=C -DMODE=EXIST
JPEG found.
$ /opt/cmake-HEAD/bin/cmake --find-package -DNAME=JPEG
-DCOMPILER_ID=GNU -DLANGUAGE=C -DMODE=COMPILE
$ /opt/cmake-HEAD/bin/cmake --find-package -DNAME=JPEG
-DCOMPILER_ID=GNU -DLANGUAGE=C -DMODE=LINK

A common mistake when using custom commands is to list the output of a
command in multiple targets that may build in parallel. Warn against
this case in the documentation and suggest a better approach.
8555c2b Look for VCExpress as a possible build tool as well as devenv.
ed0075b Use relative paths for custom command inputs.
38368d5 Revert "With very long file names, VS 2010 was unable to compile files."
8cd66dc Use devenv instead of msbuild for vs2010.
For source files we use full paths. This allows for longer directory
names with VS2010. However, the use of full paths causes the GUI
to not display the custom commands.
As discussed, this adds a switch CMAKE_DISABLE_FIND_PACKAGE_<name>,
which, when set to TRUE, keeps the find_package() command from executing.
When the package is REQUIRED at the same time, an error is generated.

The workaround added by commit 7e92f0b4 (Hack to make echo command work
properly in mingw32-make, 2006-10-05) and updated by commit 69356d8a
(Juse use cmake -E echo instead of the native echo, 2006-10-13) no
longer seems necessary with modern mingw32-make. Furthermore it slows
performance due to the time spent loading a cmake process instead of
plain echo.
Do not require the C language to be enabled to do lib->lib64 conversion.
The check was originally added by commit a5825cd1 (check in new find
stuff, 2006-03-02) to ensure that CMAKE_SIZEOF_VOID_P is set. Since
commit 3fdf1411 (FIND_LIBRARY should not require CMAKE_SIZEOF_VOID_P,
2008-02-11) the code following the check does not fail when the variable
is not set, so just remove the original check. This allows conversion
for any language that is enabled so long as the address size is known.

When add_test(NAME) is called without the CONFIGURATIONS argument then
the test is intended to run in any configuration. In multi-config
generators like the VS IDE and Xcode tests created by add_test(NAME) can
only be run when testing a known configuration (otherwise there is no
way to generate the test command line). If no test command line is
known for a particular configuration, or if no configuration is given to
ctest, report the test as not run instead of silently skipping it.
Also fix CMake's own TestsWorkingDirectory test invocation to correct a
previously silent failure exposed by this change.
When generating per-config blocks in test and install scripts replace
the form
IF()
# config == A
ENDIF()
IF()
# config == B
ENDIF()
with
IF()
# config == A
ELSEIF()
# config == B
ELSE()
# no config matches
ENDIF()
for clarity and to support the else() case cleanly.

In cmMakefile.cxx GetCMakeCFGInitDirectory is replaced with
GetCMakeFilesDirectory for .rule files. In some cases with
external projects, that directory will not exist. With vs10
the .rule files must exist or the rule will run with every build.
This fix creates the path that the .rule file is in. In addition,
it is now a CMake error if the .rule file can not be created.
A post-build phase of each target invokes the XCODE_DEPEND_HELPER.make
file to erase any targets that link to it. Narrow the set of targets
tested by each post-build phase to those that depend on the newly
completed target. This avoids removing files from partially built
unrelated targets that happen to be building in parallel.

srand(force_seed? seed : cmSystemTools::RandomSeed());
^ ~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~
Use static_cast to avoid warnings like
conversion to ‘unsigned int’ from ‘__time_t’ may alter its value
conversion to ‘unsigned int’ from ‘__suseconds_t’ may alter its value
We do not care if the value is truncated because we are looking for just
32 bits anyway.
The Sun compiler does not provide the proper vector constructor to
initialize it from an iterator pair of a non-matching type. Extend the
ParseUnixCommandLine API to provide a vector of the proper type so no
conversion is needed.
The naive time(0) seed is unique only within one second. Instead try to
read a real source of entropy and otherwise fall back to a combination
of the process id and high-resolution time.
Older versions of GCC, the HP compiler, and the SGI MIPSpro compiler do
not like the use of make_pair in this case and the conversions it
requires:
a value of type "const char *" cannot be used to initialize an entity
of type "char [1]"
/usr/include/g++-3/stl_pair.h:68: assignment of read-only location
Instead use a map lookup pattern already used throughout the rest of our
source tree.
Under Windows "locationURI" must be used for virtual folders, while
"location" must be used only for linked folders. Under Linux it doesn't
seem to matter.

The system package registry is under HKEY_LOCAL_MACHINE\SOFTWARE which
has separate views for 32-bit and 64-bit applications. Look in both
views, but prefer the architecture matching the build target platform.
Generalize the "user package registry" created by commit ed0650f6 (Teach
find_package to search a "package registry", 2009-09-01). Define a
corresponding "system" registry key under HKEY_LOCAL_MACHINE. This
gives package installers a place to create a registry value that points
at the right location for find_package() to locate the package.
Delete only REG_SZ entries that are specifically detected to point to
invalid paths. This will allow future versions to add other value types
for different purposes.

06fcbc4 VS10: Fix working directory of consecutive custom commands (#11938)
Use the pattern
setlocal
...
endlocal & call :cmErrorLevel %errorlevel% & goto :cmDone
:cmErrorLevel
exit /b %1
:cmDone
if %errorlevel% neq 0 goto :VCEnd
in custom commands to preserve the %errorlevel% from inside the
setlocal/endlocal block.
The setlocal/endlocal and errorlevel pattern added by commit 06fcbc47
(VS10: Fix working directory of consecutive custom commands, 2011-04-08)
does not work well in VS 7.1. Restore the original behavior for VS
versions that do not need the new behavior.
Copy the files specified in CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA to the right
directory when packaging components. This fixes#12061.

The parent commit assumed that "cd /d" would work in all Windows shells.
While all modern versions of windows have shells that support it, the
shells used by NMake and Borland make do not. Borland make does not
seem to even support changing drive letters with "d:". Just revert the
feature for all make tools except MinGW where the shell is known to
support this feature.
Teach cmLocalUnixMakefileGenerator3::CreateCDCommand to change working
directories for make tools using a Windows shell using "cd /d" instead
of just "cd". This tells the shell to change the current drive letter
as well as the working directory on that drive.
Commit abaa0267 (When the working directory for a custom command is on
another drive..., 2007-12-17) fixed the same problem for VS IDE
generators as reported by issue #6150.
The VS 10 msbuild tool uses a single command shell to invoke all the
custom command scripts in a project. Isolate the environment and
working directory of custom commands using setlocal/endlocal. The
form of each command is
set errlev=
setlocal
cd c:\work\dir
if %errorlevel% neq 0 goto :cmEnd
c:
if %errorlevel% neq 0 goto :cmEnd
command1 ...
if %errorlevel% neq 0 goto :cmEnd
...
commandN ...
if %errorlevel% neq 0 goto :cmEnd
:cmEnd
endlocal & set errlev=%errorlevel%
if %errlev% neq 0 goto :VCEnd
so that all changes to the environment and working directory are
isolated within the script and the return code is preserved.
Some find modules call find_package recursively to locate a package
configuration file for the package instead of searching for individual
pieces. Commit 79e9b755 (Help recursive find_package calls in modules,
2008-10-03) taught find_package to forward the version number and EXACT
arguments through the recursive call automatically. Do the same for the
component list.
When reading archive entries from disk strip any xattr and acl entry
headers that may have been loaded from the filesystem (e.g. selinux).
These fields are only useful for backup tools and not for packaging and
distribution of software. Furthermore, the GNU tar 1.15.1 on at least
one Linux distribution treats unknown entry headers as an error rather
than a warning. Therefore avoiding such fields is necessary for archive
portability.
