Alex Neundorf 96fc5d5d07 automoc: default to strict mode, use CMAKE_AUTOMOC_RELAXED_MODE
automoc now defaults to strict mode, also with Qt4, i.e. it behaves as
the documentation says by default. I also inverted the switch
CMAKE_AUTOMOC_STRICT_MODE to CMAKE_AUTOMOC_RELAXED_MODE.
Docs and test adapted accordingly.

Brad King fa7141f5ad Add framework to detect compiler version with its id (#12408)
Teach CMakePlatformId.h to construct an "INFO:compiler_version[]" string
literal from macros COMPILER_VERSION_(MAJOR|MINOR|PATCH|TWEAK) to be
defined in CMake(C|CXX)CompilerId.(c|cpp) for each compiler.  Provide
conversion macros DEC() and HEX() to decode decimal or hex digits from
integer values.  Parse the version out of the compiler id binary along
with the other INFO values already present.

Store the result in variable CMAKE_<LANG>_COMPILER_VERSION in the format
"major[.minor[.patch[.tweak]]]".  Save the value persistently in
CMake(C|CXX)Compiler.cmake in the build tree.  Document the variable for
internal use since we do not set it everywhere yet.

Report the compiler version on the compiler id result line e.g.

  The C compiler identification is GNU 4.5.2

Report CMAKE_(C|CXX)_COMPILER_(ID|VERSION) in SystemInformation test.

Brad King afb00fef19 Add CMAKE_GNUtoMS option to convert GNU .dll.a to MS .lib
Teach the Windows-GNU.cmake platform file to look for Visual Studio
tools matching the target ABI.  Add an extra step to the link command
for shared libraries and executables that export symbols and on which a
new GNUtoMS property is set (initialized by the CMAKE_GNUtoMS option).
Tell the GNU linker to output a module definition (.def) file listing
exported symbols in addition to the GNU-format import library (.dll.a).
Pass the .def file to the MS "lib" tool to construct a MS-format DLL
import library (.lib).

Teach the install(TARGETS) command to install the MS import library next
to the GNU one.  Teach the install(EXPORT) and export() command to set
the IMPORTED_IMPLIB property pointing at the import library to use the
import library matching the tools in the importing project.

Brad King a603250a13 Load platform files that need to know the ABI when possible
Load platform files named in CMAKE_<lang>_ABI_FILES for each language
once the ABI sizeof(void*) is known.  During the first configuration
this is after the test for working compiler and ABI detection checks.
During later configurations the ABI information is immediately available
because it has been saved in CMake<lang>Compiler.cmake.

Brad King a364daf1fd Allow users to specify defaults for unset policies
Check CMAKE_POLICY_DEFAULT_CMP<NNNN> for a default when policy CMP<NNNN>
would otherwise be left unset.  This allows users to set policies on the
command line when the project does not set them.  One may do this to
quiet warnings or test whether a project will build with new behavior
without modifying code.  There may also be cases when users want to
build an existing project release using new behavior for policies
unknown to the project at the time of the release.

Brad King c592df8377 Tru64: Use full-path include directives in Makefiles (#10569)
Tru64's make(1) resolves relative paths in "include" directives with
respect to the includer.  This is inconsistent with all other known make
tools.  Note that this make tool treats the path literally so we cannot
use our standard FULL path code which escapes spaces.  Instead qualify
the paths with $(CMAKE_BINARY_DIR) to avoid the problem.

Brad King 5bfffd6f29 New version scheme to support branchy workflow
Prepare to switch to the workflow described by "git help workflows".  In
this workflow, the "master" branch is always used to integrate topics
ready for release.  Brand new work merges into a "next" branch instead.
We need a new versioning scheme to work this way because the version on
"master" must always increase.

We no longer use an even/odd minor number to distinguish releases from
development versions.  Since we still support cvs checkout of our source
tree we cannot depend on "git describe" to compute a version number
based on the history graph.  We can use the CCYYMMDD nightly date stamp
to get a monotonically increasing version component.

The new version format is "major.minor.patch.(tweak|date)".  Releases
use a tweak level in the half-open range [0,20000000), which is smaller
than any current or future date.  For tweak=0 we do not show the tweak
component, leaving the format "major.minor.patch" for most releases.
Development versions use date=CCYYMMDD for the tweak level.  The
major.minor.patch part of development versions on "master" always
matches the most recent release.

For example, a first-parent traversal of "master" might see

        v2.8.1      2.8.1.20100422    v2.8.2
           |              |              |
  ----o----o----o----o----o----o----o----o----

Since the date appears in the tweak component, the next release can
increment the patch level (or any more significant component) to be
greater than any version leading to it.  Topic branches not ready for
release are published only on "next" so we know that all versions on
master lead between two releases.

Brad King fcab87c9f8 Do not always propagate linker language preference
The commit "Consider link dependencies for link language" taught CMake
to propagate linker language preference from languages compiled into
libraries linked by a target.  It turns out this should only be done for
some languages, such as C++, because normally the language of the
program entry point (main) should be used.

We introduce variable CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES to tell
CMake whether a language should propagate its linker preference across
targets.  Currently it is true only for C++.

Brad King 07ea19ad1f ENH: Implicit link info for C, CXX, and Fortran
This teaches CMake to detect implicit link information for C, C++, and
Fortran compilers.  We detect the implicit linker search directories and
implicit linker options for UNIX-like environments using verbose output
from compiler front-ends.  We store results in new variables called

  CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
  CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES

The implicit libraries can contain linker flags as well as library
names.

Brad King 99e432508e BUG: Use link language for target name computation
The commit "Do not compute link language for LOCATION" was wrong.  The
variables

  CMAKE_STATIC_LIBRARY_PREFIX_Java
  CMAKE_STATIC_LIBRARY_SUFFIX_Java

are used for building Java .jar files.  This commit re-enables the
feature and documents the variables:

  CMAKE_EXECUTABLE_SUFFIX_<LANG>
  CMAKE_IMPORT_LIBRARY_PREFIX_<LANG>
  CMAKE_IMPORT_LIBRARY_SUFFIX_<LANG>
  CMAKE_SHARED_LIBRARY_PREFIX_<LANG>
  CMAKE_SHARED_LIBRARY_SUFFIX_<LANG>
  CMAKE_SHARED_MODULE_PREFIX_<LANG>
  CMAKE_SHARED_MODULE_SUFFIX_<LANG>
  CMAKE_STATIC_LIBRARY_PREFIX_<LANG>
  CMAKE_STATIC_LIBRARY_SUFFIX_<LANG>

Instead of making separate, repetitive entries for the _<LANG> variable
documentation, we just mention the per-language name in the text of the
platform-wide variable documentation.  Internally we keep undocumented
definitions of these properties to satisfy CMAKE_STRICT mode.
