In both files find_path() and find_library() are called with multiple
additional search PATHS which are already anyway part of the default
search dirs, so it should be safe to remove them.

What was given as comment to set_package_info(), now goes into
the PURPOSE field. It was not clear what the comment should contain,
with the PURPOSE this is much clearer now.
Alex
With the PURPOSE a project can state what the package in question
is used for in the project (as opposed to describing what the package
does in general).
TYPE can be one of OPTIONAL (default)
RUNTIME - not needed for building, only at runtime
RECOMMENDED - as OPTIONAL, but you should really have it
REQUIRED - cmake will fail if one of these is not found
This can be set using the new function set_package_properties()

This patch adds two macros cmake_push_check_state() and

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:

-DCOMPILER_ID=GNU -DLANGUAGE=C -DMODE=EXIST
JPEG found.

If FindMPI can't interrogate any of the available compilers, it attempts to compile simple MPI
programs with CMAKE_${lang}_COMPILER. If this works, it uses that as MPI_${lang}_COMPILER.
This allows MPI to be discovered on Cray XT/XE systems, where modules are used and cc, CC, and ftn
compilers *are* MPI compilers.
Without this, regular swig (not 2.0) executable is not found
automatically.
Commit 55b7c87e (Add support for new swig 2.0 application, 2011-03-28)
added support for finding swig 2.0 at the (accidental) expense of not
finding 1.x. Fix this regression.
Patch from Aaron C. Meadows
Adds support for detecting VS 2010 SP1
Also improves performance using CMAKE_CXX_COMPILER if it is available
and for robustness falls back using try_compile() and try_run()
1ed19bc multiarch: Set CMAKE_LIBRARY_ARCHITECTURE_REGEX for Linux|Hurd|kFreeBSD
52a6ed2 Test find_package multiarch support (#12037)
b41ad3b Teach find_(library|package) about Linux multiarch (#12037)
Fix typo introduced by commit e28c16b4 (Split GNU compiler information
files, 2009-12-02).
Reported-by: Campbell Barton <ideasman42@gmail.com>
Suggested-by: Michael Hertling <mhertling@online.de>
* Fix linux CMAKE_LIBRARY_ARCHITECTURE_REGEX to support armel-linux-gnueabi.
* Add CMAKE_LIBRARY_ARCHITECTURE_REGEX on kFreeBSD.
* Add CMAKE_LIBRARY_ARCHITECTURE_REGEX on GNU (Hurd).
Also regex is improved to support quadlets. Even if I have not seen this
in the wild yet, reportedly they are possible.
Workaround an issue where users wanted to use Boost_LIBRARIES with the
install() command and debug/optimized keywords were interfering. Now
debug/optimized keywords are removed if the release & debug library
are the same.
Implement support for multiarch as specified here:
http://wiki.debian.org/Multiarchhttps://wiki.ubuntu.com/MultiarchSpec
Detect the <arch> part of <prefix>/lib/<arch> from the implicit library
search path from each compiler to set CMAKE_<lang>_LIBRARY_ARCHITECTURE.
Define CMAKE_LIBRARY_ARCHITECTURE using one of these values (they should
all be the same). Teach the find_library and find_package commands to
search <prefix>/lib/<arch> whenever they would search <prefix>/lib.

When the path to "resolved_embedded_item" was shorter than

fail with a cmake error like:
"string end index: 110 is out of range 0 - 85"
Detect when the path of resolved_embedded_item is too short
to be embedded in the bundle, and report the proper error
message, so the poor developer reading it has a snowball's
chance of actually fixing the issue.

a32a633 FindMPI: Fix documentation formatting
706b73e FindMPI: Handle multiple languages
Users can now supply MPI_COMPILER, MPI_INCLUDE_PATH, MPI_LIBRARY,
and others as with the old FindMPI. These are mapped to their
respective equivalents for C and CXX. Fortran is not touched, as
there was no Fortran support in the old FindMPI.
The custom error message that mentions PREFIX/lib/InsightToolkit is not
accurate for ITKv4. Just use the more generic message that find_package
generates by default. This module is now almost a no-op but exists to
tell find_package to look for the InsightToolkit name as well as ITK.
The previous commit added --non-interactive as a "side effect"
of turning on SVN_TRUST_CERT. While reviewing that commit, we
decided all ExternalProject svn usage should be non-interactive.
That way, if there's any sort of problem, svn will return an
error right away rather than hang forever waiting for input...
Which adds --non-interactive and --trust-server-cert to the svn
checkout and update command lines. This allows ExternalProject
clients to pull from an https:// based svn server even though
the server may not have a valid or trusted certificate.
Caveat emptor: I would NOT recommend using this except as a
short-term work-around. Rather, the server should have a valid,
trusted certificate, or the client should be using "http" instead
of "https".

The XL toolchain supports shared object files stored in archives. Since
CMake lists libraries on link lines by full path it is common for a
shared library link line to contain the path to an archive file.
When linking a shared library the compiler front-end by default runs
CreateExportList to construct the list of symbols to be exported.
Unfortunately it passes all files found on the command line to the tool
so archive and library files get processed along with the object files.
The tool returns a list of all symbols in all objects, archives, and
libraries on the command line. This causes the linker to copy every
object file out of every archive into the shared library whether they
are dependencies of the original object files or not.
Work around this problem by running CreateExportList ourselves with just
the original object files intended for inclusion in the shared library.
Then pass the list it produces on the link line to prevent the compiler
front-end from constructing its own. This tells the linker to export
only the symbols provided by the original source files of the shared
library.
Factor duplicate information out of Compiler/XL-<lang>.cmake modules
into a macro in a new Compiler/XL.cmake module. Invoke it from the
per-language files to produce the original settings.
Since commit e1729238 (Add initial XL C compiler flags for safer builds,
2009-09-30) CMake sets the initial XL C flags to include "-qthreaded"
and "-qhalt=e". Do the same for C++ and Fortran with this toolchain.

The AMD64 ABI document http://www.x86-64.org/documentation/abi.pdf
does specify that 64bits binary libraries should end up in <prefix>/lib64
and 32bits ones in <prefix>/lib. All but debian based distros do so,
and some like OpenSUSE even enforce the rule when packaging with RPM
and refuse to build the RPM if this is not the case.
After some discussion (see the bug notes) we cannot do that behind
the scene and the current fix supposes that the user shall use
the CMAKE_INSTALL_LIBDIR variables content in its INSTALL rules if
he wants to put the lib in the right place. CMAKE_INSTALL_LIBDIR
shall have the appropriate value depending on the Linux distribution
found and 32/64bitness of the host.
The cross-compiling case (even 32bits compile on a 64bits host)
is not handled.
The Cray Fortran compiler started using module init symbols in version 7.3.2.
Starting in commit 71287734 (Teach FortranC interface for Intel, PGI, and gcc
4.2, 2009-08-05) we provide C versions of the module init symbols so that the
detection executable can link when the C versions of the module-mangled symbols
are picked up.
If no C module-mangled symbol matches then we cannot let the C module init
symbol appear because it will be duplicated by the Fortran copy that provides
the module-mangled symbol. This was first handled for the PathScale compiler
in commit 21faaa5d (FortranCInterface: Fix PathScale detection, 2010-01-22) and
commit 46858720 (FortranCInterface: Fix PathScale detection again, 2010-02-16).
Handle it now for the Cray compiler too.

d099546 Factor old-style -D flags out from -I flag generation
Also, comment out all "debugging" calls to message() that helped
us interpret the output on other platforms when running on the
dashboard clients.
Using ERROR_QUIET avoids unnecessary stderr output while calling
external tools to determine the processor count. If there's an
error parsing the output, we set the count to 0 anyhow.
Also, the test will fail on a CMake dashboard run if the count
comes back equal to 0.
Now that the code is "done"-ish, remove the debugging output.
Expect no output on stdout or stderr when calling the
ProcessorCount function from now on.
This check if the function exists and the prototype we want to use is
correct. There are still functions which have different prototypes on
different UNIX systems.
The GNU 4.x toolchain on MinGW (and therefore MSYS) allows compiler
options to be passed via response files. Use this to pass include
directory -I options. This allows the include file search path to be
very long despite shell and mingw32-make command line length limits.
Adjust whitespace to make the output of "--help-module FindMPI" look
good. Also separate the comment containing the copyright and license
notice so it does not appear in the documentation.
Adds support for:
- MPI_<lang>_COMPILER and other useful variables for C, CXX, Fortran
- Better compiler interrogation (handles mvapich)
- Supports specifying an MPI compiler name directly on the command line
without and absolute path, e.g.: cmake -D MPI_CXX_COMPILER=mpixlC
- Better compiler name searching tries to match MPI compiler to regular
CMAKE_<lang>_COMPILER_ID, if it's available.
Gets rid of:
- MPI_LIBRARY, MPI_EXTRA_LIBRARY cache variables. These and other old
vars are still exported for backward compatibility, but they're not
cached.
Also, add message output (temporarily) for gathering data
on all the dashboard machines. After the test runs on the
overnight dashboards tonight, I'll comment out the message
output and commit/push again.

Also add a script-based test of the new module.

Commit 6a61a8a5 (Honor module .def files with MinGW tools, 2011-02-21)
set CMAKE_LINK_DEF_FILE_FLAG to "-Wl," to enable passing .def files to

know how to translate "-Wl,/c/..." to "c:/..." and complain that the
file does not exist. Instead set the flag to just "" which tells CMake
it can pass the file through the front-end with no special flag.

the -o option is ignored and the object file is example.o. Performing
the same experiment on the underlying compiler tool or with the mpicc

to be specific to mpif77.

This commit changes the way how the assembler support works in cmake.
The language "ASM" now always uses the C/Cxx compiler instead
of the assembler directly. This fixes#8392, assembler files are
not preprocessed.
If one wants to use the assembler directly, the specific
assembler "dialect" has to be enabled. I.e. to get as/gas,
you have to use now ASM-ATT, the same way for ASM_MASM and ASM_NASM.
Implemented this now for gcc.
SunStudio, IBM, HP and Intel still todo.

The FindPackageHandleStandardArgs module was originally created outside
of CMake. It was added for CMake 2.6.0 by commit e118a627 (add a macro
FIND_PACKAGE_HANDLE_STANDARD_ARGS..., 2007-07-18). However, it also
proliferated into a number of other projects that at the time required
only CMake 2.4 and thus could not depend on CMake to provide the module.
CMake's own find modules started using the module in commit b5f656e0
(use the new FIND_PACKAGE_HANDLE_STANDARD_ARGS in some of the FindXXX
modules..., 2007-07-18).
Then commit d358cf5c (add 2nd, more powerful mode to
find_package_handle_standard_args, 2010-07-29) added a new feature to
the interface of the module that was fully optional and backward
compatible with all existing users of the module. Later commit 5f183caa
(FindZLIB: use the FPHSA version mode, 2010-08-04) and others shortly
thereafter started using the new interface in CMake's own find modules.
This change was also backward compatible because it was only an
implementation detail within each module.
Unforutnately these changes introduced a problem for projects that still
have an old copy of FindPackageHandleStandardArgs in CMAKE_MODULE_PATH.
When any such project uses one of CMake's builtin find modules the line
include(FindPackageHandleStandardArgs)
loads the copy from the project which does not have the new interface!
Then the including find module tries to use the new interface with the
old module and fails.
Whether this breakage can be considered a backward incompatible change
in CMake is debatable. The situation is analagous to copying a standard
library header from one version of a compiler into a project and then
observing problems when the next version of the compiler reports errors
in its other headers that depend on its new version of the original
header. Nevertheless it is a change to CMake that causes problems for
projects that worked with previous versions.
This problem was discovered during the 2.8.3 release candidate cycle.
It is an instance of a more general problem with projects that provide
their own versions of CMake modules when other CMake modules depend on
them. At the time we resolved this instance of the problem with commit
b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake
everywhere, 2010-09-28) for the 2.8.3 release.
In order to address the more general problem we introduced policy
CMP0017 in commit db44848f (Prefer files from CMAKE_ROOT when including
from CMAKE_ROOT, 2010-11-17). That change was followed by commit
ce28737c (Remove usage of CMAKE_CURRENT_LIST_DIR now that we have
CMP0017, 2010-12-20) which reverted the original workaround in favor of
using the policy. However, existing project releases do not set the
policy behavior to NEW and therefore still exhibit the problem.
We introduced in commit a364daf1 (Allow users to specify defaults for
unset policies, 2011-01-03) an option for users to build existing
projects by adding -DCMAKE_POLICY_DEFAULT_CMP0017=NEW to the command
line. Unfortunately this solution still does not allow such projects to
build out of the box, and there is no good way to suggest the use of the
new option.
The only remaining solution to keep existing projects that exhibit this
problem building is to restore the change originally made in commit
b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake
everywhere, 2010-09-28). This also avoids policy CMP0017 warnings for
this particular instance of the problem the policy addresses.
In commit 295b5b60 (Honor CMAKE_USER_MAKE_RULES_OVERRIDE in try_compile,
2010-06-29) we started passing the value of this variable when building
a try_compile project. If the variable contains a relative path it must
be treated with respect to the file where it is first used. Ensure that
the value is converted to a full path so that it is correctly referenced
in the try_compile projects.
The module header was being placed in the source tree before. Thanks to
Marcel Loose for the patch, this ensures the file is written to the
build tree.
