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.

Todd Gamblin 1221581aa8 Teach find_* commands to ignore some paths
Add platform configuration variable CMAKE_SYSTEM_IGNORE_PATH and user
configuration variable CMAKE_IGNORE_PATH.  These specify a set of
directories that will be ignored by all the find commands.  Update
FindPackageTest so that several cases will fail without a functioning
CMAKE_IGNORE_PATH.

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.

Brad King 2b5d97419f ENH: Do not compute link language for LOCATION
The LOCATION property requires the full file name of a target to be
computed.  Previously we computed the linker language for a target to
look up variables such as CMAKE_SHARED_LIBRARY_SUFFIX_<LANG>.  This led
to locating all the source files immediately instead of delaying the
search to generation time.  In the future even more computation will be
needed to get the linker language, so it is better to avoid it.

The _<LANG> versions of these variables are undocumented, not set in any
platform file we provide, and do not produce hits in google.  This
change just removes the unused feature outright.

Brad King 98c51ff6dc ENH: Overhaul CMake version numbering
This moves the version numbers into an isolated configured header so
that not all of CMake needs to rebuild when the version changes.

Previously we had spaces, dashes and/or the word 'patch' randomly chosen
before the patch number.  Now we always report version numbers in the
traditional format "<major>.<minor>.<patch>[-rc<rc>]".

We still use odd minor numbers for development versions.  Now we also
use the CCYYMMDD date as the patch number of development versions, thus
allowing tests for exact CMake versions.

Brad King cb788e8f6d ENH: Re-enable system include dir suppression
This creates variable CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES to
specify implicit include directories on a per-language basis.  This
replaces the previous platform-wide variable.  It is necessary to
avoid explicit specification of -I/usr/include on some compilers
(such as HP aCC) because:

  1.) It may break ordering among system include directories defined
      internally by the compiler, thus getting wrong system headers.
  2.) It tells the compiler to treat the system include directory
      as a user include directory, enabling warnings in the headers.

See issue #8598.
