Visual Studio 6 does not recognize .cc as a C++ extension by default.
Simplify the test to be C-only and use a .c extension.

ENH:  For #7433, add documentation that directories also can be specified to
      update the translation files.

The recent fix to avoid including flags in dependency inferral also
dropped them from chaining of dependencies through targets.  This fix
restores chaining of flags through known dependency lists while still
leaving them out of inferred dependency lists.

ENH: Changes that allow configuring/building BundleTest test separately from the main CMake build. (Eliminate reference to CMake_SOURE_DIR.)

This change introduces a new algorithm for link line construction.  The
order it computes always begins with the exact link line specified by
the user.  Dependencies of items specified by the user are tracked, and
those that are not already satisified by the line are appended to it at
the end with minimal repeats.  This restores the behavior of CMake 2.4
and below while still fixing some of its bugs.  See issue #7546.

In cmComputeLinkDepends link items that look like flags (starting in
'-') should not be included in dependency inferral.  They are not
libraries and therefore have no dependencies.  They should just be
passed through to the final link line unchanged.  See issue #7546.

In cmComputeLinkDepends we should treat an empty configuration name as
equivalent to no specific configuration at all.

BUG: Do not use "Default" as a language, remove 2nd occurence of "English", and remove three other languages not supported by older versions of NSIS. Tested with version 2.18 of NSIS on gaia.kitware.

ENH:  Add comments about pre-processor defines and moc.

ENH:  Use COMPILE_DEFINTIONS instead of DEFINITIONS.

ENH:  Add -DWIN32 for moc on Windows.  Final fix for #7465.

ENH:  Add -D preprocessor defines to the moc commands.
      Needed to fix #7465.

This introduces the unset() command to make it easy to unset CMake
variables, environment variables, and CMake cache variables.  Previously
it was not even possible to unset ENV or CACHE variables (as in
completely remove them).  Changes based on patch from Philip Lowman.
See issue #7507.

ENH: Add the RECURSE_SYMLINKS_OFF flag to the FILE GLOB_RECURSE command. Exposes the recently added kwsys capability that prevents recursing through symlinks to CMake scripts.

Some native build tools, particularly those for cross compiling, may
have a limit on the length of the full path to an object file name that
is lower than the platform otherwise supports.  This change allows the
limit to be set by the project toolchain file through the variable
CMAKE_OBJECT_PATH_MAX.

ENH: Add RecurseThroughSymlinks data member to kwsys::Glob. Allows recursive globs to skip symlinks when necessary. Default to true for backwards compatible behavior. Used from the ctest coverage handler to avoid recursing through the '/Applications' directory on the Mac looking for *.da files... Should fix the hangs reported recently by Mac CMake dashboard submitters.

It is useful to be able to test if a target has been created.  Often
targets are created only inside conditions.  Rather than storing the
result of the condition manually for testing by other parts of the
project, it is much easier for the other parts to just test for the
target's existence.  This will also be useful when find-modules start
reporting results with IMPORTED targets and projects want to test if a
certain target is available.

According to "man select" on Linux it is possible that select() lies
about data being ready on a pipe in some subtle cases.  We deal with
this by switching to non-blocking i/o and checking for EAGAIN.  See
issue #7180.
