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).
Commit aaa88d33 (Build large archives incrementally, 2008-08-04)
hard-coded rules to create static archives incrementally in each
language information file. Set each rule conditionally to allow
compiler and platform information files to override the language
default rules.

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.

This puts the new search behaviour for included files in action, i.e.
now when a file from Modules/ include()s another file, it also gets the
one from Modules/ included, i.e. the one it expects.

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
TMS320C6x C/C++ Compiler v6.1.11

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.

Since commit aff31479 (Modernize GNU compiler info on Windows,
2009-12-02) the file Modules/Platform/Windows-g++.cmake has been unused.
It just includes the non-existent Modules/Platform/Windows-gcc.cmake so
remove it outright.
This moves Intel compiler info on Windows into new-style modules
Platform/Windows-Intel-<lang>.cmake
using language-independent helper module
Platform/Windows-Intel.cmake
to define macros consolidating the information.
Commit 4430bccc (Change the way 32/64 bit compiles are detected with
MSVC and intel, 2009-11-19) added detection of the target processor to C
and CXX language builds with MS and Intel tools. Do the same for Intel
Fortran for Windows (ifort). Use /machine:<arch> to link executables.

Escaped the @var@ in the file writes - this was being expanded at file
write and so not causing a reconfigure at the right time. I also took
care of build up lists of lists in the variables, especially important
for things like MPI_EXTRA_LIBRARY. Added some error checking, and use
the tmp_dir for initial cache file.
On Windows the limit for command line arguments is 8192 characters, and
this was limiting longer paths with some of our more nested projects
such as Library. Placing the -D arguments into CMAKE_CACHE_ARGS will
write out an initial cache file, that will be passed to CMake with a -C
argument as the initial cache.
By forcing the cache variables we preserve the existing behavior with
-D, to change the values of cache variables in our inner projects.
On Linux the NAG Fortran compiler uses gcc under the hood to link. Use
"-Wl,-v" to pass "-v" to the underlying gcc compiler to get verbose link
output. Detect the NAG Fortran directory (using -dryrun) and then honor
object files in the directory referenced in the implicit link line.
Pass real linker options with "-Wl,-Xlinker,". The -Wl, gets through
the NAG front-end and the -Xlinker gets through the gcc front-end.
The Numerical Algorithms Group (NAG) Fortran compiler does not document
a preprocessor macro to identify it. Check for identifying output using
the -V option.
Teach CMakeFortranInformation to use default flags only for variables
that have not been set at all, rather then not set or empty. This will
allow platform or compiler-specific information files to set empty
values without getting the defaults.
The NAG Fortran compiler implicitly passes object files by full path to
the linker. Teach CMakeParseImplicitLinkInfo to parse object files that
match some tool-specific regular expression.
FindTCL.cmake switched variables in the FIND_LIBRARY invocation. The
FIND_LIBRARY() statement for TCL used the TK variables and vice versa.
This patch reverses that into the right usage.
