This creates an "IPO" test that builds some other tests as subdirectories
while enabling INTERPROCEDURAL_OPTIMIZATION.  See issue #9615.

This commit creates target and directory properties to enable the Intel
interprocedural optimization support on Linux.  Enabling it adds the
compiler option '-ipo' and uses 'xiar' to create archives.

See issue #9615.

This creates cmTarget::GetFeature and cmMakefile::GetFeature methods to
query "build feature" properties.  These methods handle local-to-global
scope and per-configuration property lookup.  Specific build features
will be defined later.

We create cmMakefileTargetGenerator::AddFeatureFlags to consolidate
addition of language flags.  Currently it just adds the flags from
generic per-language flag variables (AddLanguageFlags).

This renames the variable '_intel_xair_hints' to '_intel_xiar_hints'.

There is confusion whether the file "currently being processed" inside a
function or macro is the file containing the definition or not.  This
commit explicitly describes the behavior.  See issue #9646.

This new test checks Modules/*.cmake for the required copyright notice.

In VS 6, 7, and 7.1 solutions we implement

  add_dependencies(myexe mylib) # depend without linking

by creating an intermediate mylib_UTILITY target with dependencies

  myexe -> mylib_UTILITY -> mylib

to avoid linking myexe to mylib.  Previously these extra targets were
only added to the solution files in an ancestor directory of that
defining mylib.  For example, in the project:

  # CMakeLists.txt
  project(TOP)
  add_subdirectory(A)
  add_subdirectory(b)

  # A/CMakeLists.txt
  add_library(mylib ...)

  # B/CMakeLists.txt
  project(B)
  add_executable(myexe ...)
  add_dependencies(myexe mylib)

the solution for TOP would have mylib_UTILITY but the solution for B
would not even though it pulls in mylib through the dependency.  This
commit fixes solutions generated in other directories so that any
solution that has mylib will get mylib_UTILITY also.

See issue #9568.

This commit cleans up the declaration, definition, and invocations of
the GetTargetSets method and related code.  There is no change in
function except to make the method virtual.

Some bugfixes, also added public function for closer integration btwn GoogleTest & CTest, contributed by Dan Blezek.

Other minor changes:
* Enhanced documentation & added examples
* _INCLUDE_DIRS and _LIBRARIES was being set regardless of _FOUND
* Fixed status message to include library rather than include dir
* Improved detection of MSVC compiled libraries
* Added a variable (GTEST_BOTH_LIBRARIES) for libgtest + libgtest_main

Eliminate ExternalProject's use of CMAKE_CFG_INTDIR subdir for Makefile generators. It was causing problems with parallel make -j invocations. Keep it for multi-configuration build systems so that Debug and Release stamp files remain separate.

The commit "Use target dependency closure for VS 6 solutions" removed
use of the CreatedProjectNames list, so we remove it.

This teaches the VS 6 IDE generator to use the transitive closure of
target dependencies.  This re-uses much of the implementation already
done for the other VS>6 generators.  See issue #8223 and issue #9568.

We move cmGlobalVisualStudio7Generator::OrderedTargetDependSet up to
cmGlobalVisualStudioGenerator so it can be re-used for other VS
versions.  See issue #9568.

Some find-modules use get_filename_component() to expand registry
values.  We need to look in both the 32-bit and 64-bit registry views
when expanding values.  We prefer the one that the target application
would see.  See issue #8792.

This method centralizes tests for whether CMAKE_SIZEOF_VOID_P is 8.

Fix warnings in CMake source code. Suppress warnings in Lexer and Parser files that are 'too hard' to fix.

When building through NMake with VS 6, the module definition file must
be passed without spaces in the path.  This is because 'cl -link' does
not escape the spaces when passing the value on to the linker.

This commit adds some default initial C flags for the XL compiler.  The
most important is "-qhalt=e" which causes the compiler to error-out on
non-severe error messages.  This is necessary to get try-compiles to
fail when bad arguments are passed to a function.

This moves platform-independent XL compiler flags into separate
"Compiler/XL-<lang>.cmake" modules.  Platform-specific flags go in
"Platform/<os>-XL-<lang>.cmake" modules.

Since Haiku does not have /usr (and therefore /usr/local), this commit
changes the default install prefix to the equivalent directory of
/boot/common.

See issue #9607.

This adds a "ModuleDefinition" test enabled when using MSVC tools.  It
checks that .def files can be used to export .dll and .exe symbols and
create corresponding .lib files that can be linked.  See issue #9613.

We recognize .def source files and map them to the /DEF:<file> option in
the MSVC tools.  Previously this worked only for shared libraries.  This
commit cleans up the implementation and makes it work for executables
too.  See issue #9613.
