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.

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.

set CMAKE_LINK_DEF_FILE_FLAG to "-Wl," to enable passing .def files to
the linker on MinGW. However, older GNU tools in the MSYS shell do not
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.

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.

cd626ea For macros make sure the FilePath points to a valid pointer in the args.
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.
The parent commit added a warning message whenever a required file
does not exist.
As it turns out, the "required" files never exist when built with
Visual Studio Express editions. Add a variable to suppress these
warning messages because only packagers or naive includers of
this file will care to see such warning messages.
We want to warn about this condition by default so that people who
are using InstallRequiredSystemLibraries without understanding it
fully will have a chance of understanding why it's not working in
the event of missing required files.
But we also want to give projects the ability to suppress this warning
(by "project's choice default") so that they can encourage users who
are restricted to using an Express edition to build their project.
Packagers should explicitly use...
-DCMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS=OFF
...when building releases. That way, their release build process will warn
them about any missing files, but only if their project CMakeLists files
use a construct similar to CMake's:
IF(NOT DEFINED CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS)
SET(CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS ON)
ENDIF()
Thanks to "J Decker" on the CMake mailing list for pointing out
that one of the MSVC10_CRT_DIR settings was using "VC90" instead
of "VC100".
After fixing that, I added the code to generate a CMake warning
if one of the files we think is "required" does not exist.
Then, with VS10, there were several other problems that the
warning revealed:
- MSVC10_REDIST_DIR needed more PATHS to be found correctly
- the 64-bit directory is named "x64" now, not "amd64" as in
previous VS versions
- manifest files no longer exist as separate files in the
redist subdirectories (they must be built-in as resources
to the dlls...?)
The check works for macros, functions, and variables, but not for types
or enumeration values. Clearly describe the behavior of the check with
respect to each symbol type.

Control the root directory of the default directory presented to
the end user of an NSIS installer by a CPack variable.
Previously, the value used in the NSIS script was $PROGRAMFILES,
which is equivalent to the "ProgramFiles" environment variable.
That default value is still the same, but now a project may
override the value by setting this new variable.
Introduced an additional variable, Python_ADDITIONAL_VERSIONS, to both
FindPythonLibs and FindPythonInterp. Changed FindPythonInterp to loop
over versions rather than hardcoding all versions (more like libs).

Unset VS_UNICODE_OUTPUT when executing a command whose output
is being logged to a file. Previously, running Microsoft tools
in sub-processes of Visual Studio would send their output to
the Visual Studio output pipe named by this environment variable.
Unsetting it forces the output back to the normal stdout and stderr
channels where cmake can intercept it and direct it to the
appropriate log files.
MUI_FINISHPAGE_RUN is frequently used with NSIS and provides a checkbox
on the finish page of an installer which specifies whether the specified
executable should be run when the installer exits. This commit adds support
for this setting in CPack.
NSIS installers default to assuming the executables exist in a
directory named "bin" under the installation directory. As this
isn't usual for Windows programs, the addition of this variable
allows the customization of this directory and links still to be
created correctly.
Add support to InstallRequiredSystemLibraries to only install
debug libraries when both debug and release versions are available.
This is as if you are building a debug package then only the debug
versions are needed but not the release.
InstallRequiredSystemLibraries currently defaults to installing to
bin on WIN32 and lib otherwise. This patch allows you to configure
this by using the variable CMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION.
It also switches the logic to use a single INSTALL(PROGRAMS) command
rather than two deprecated uses of the INSTALL_PROGRAMS command.
In InstallRequiredSystemLibraries the documentation details the
variable CMAKE_SKIP_INSTALL_RULES to skip installation. This
actually doesn't do anything, the variable required is named
CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP. This commit amends the
documentation to point to the correct variable.

Since commit 70c2dc8a (Make compiler id detection more robust,
2008-03-10) we store compiler identification strings in test binaries
using the form
char* info = "info";
Use the const-correct
char const* info = "info";
form instead. This allows the C++ compiler identification to work with
"-Werror -Wall" or equivalent flags if the compiler would warn about
const-to-non-const conversion.
The TI DSP compiler predefines "__TI_COMPILER_VERSION__". Use this to
identify the C and C++ compilers. For assembler language the C compiler
executable is used:
$ cl6x -h

Use this command-line option and output to recognize the assembler.
The Mac linker defines flag -headerpad_max_install_names but not all
front-ends recognize the flag and pass it through (many did in the past,
such as the Apple port of GCC). Use the -Wl, option prefix to tell
front-ends to pass it through without trying to interpret it.
One of Cygwin's goals is to build projects using the POSIX API with no
Windows awareness. Many CMake-built projects have been written to test
for UNIX and WIN32 but not CYGWIN. The preferred behavior under Cygwin
in such projects is to take the UNIX path but not the WIN32 path.
Unfortunately this change is BACKWARDS INCOMPATIBLE for Cygwin-aware
CMake projects! Some projects that previously built under Cygwin and
are Cygwin-aware when they test for WIN32 may now behave differently.
Eventually these projects will need to be updated, but to help users
build them in the meantime we print a warning about the change in
behavior. Furthermore, one may set CMAKE_LEGACY_CYGWIN_WIN32 to request
old behavior during the transition.
Normally we avoid backwards incompatible changes, but we make an
exception in this case for a few reasons:
(1) This behavior is preferred by Cygwin's design goals.
(2) A warning provides a clear path forward for everyone who may see
incompatible behavior, and CMAKE_LEGACY_CYGWIN_WIN32 provides a
compatibility option. The warning and compatibility option both
disappear when the minimum required version of CMake in a project is
sufficiently new, so this issue will simply go away over time as
projects are updated to account for the change.
(3) The fixes required to update projects are fairly insignificant.
Furthermore, the Cygwin distribution has no releases itself so project
versions that predate said fixes tend to be difficult to build anyway.
(4) This change enables many CMake-built projects that did not
previously build under Cygwin to work out-of-the-box. From bug #10122:
"I have built over 120 different source packages with (my patched)
CMake, including most of KDE4, and have found that NOT defining
WIN32 on Cygwin is much more accurate." -- Yaakov Selkowitz
A fully compatible change would require patches on top of these project
releases for Cygwin even though they otherwise need not be aware of it.
(5) Yaakov has been maintaining a fork of CMake with this change for the
Cygwin Ports distribution. It works well in practice. By accepting the
change in upstream CMake we avoid confusion between the versions.
CMake itself builds without WIN32 defined on Cygwin. Simply disable
CMAKE_LEGACY_CYGWIN_WIN32 explicitly in our own CMakeLists.txt file.
