MS tools have a limit on the number of symbols that can be listed
in a `.def` file. If multiple `.obj` files provide a symbol then
avoid listing it more than once in the generated `.def` file to
avoid counting toward the limit.
Refactoring in commit v3.4.0-rc1~74^2~1 (MSVC: Rewrite manifest file
handling with Makefile and Ninja, 2015-09-15) broke handling of this
option. Fix it and add a test case.
The cmMakefile should get a fully prepared snapshot and not clobber its
definitions. It should eventually be able to process list files from any
starting-point snapshot, though that is some refactoring away still.
Classify .manifest sources separately, add dependencies on them, and
pass them to the MS manifest tool to merge with linker-generated
manifest files.

Add a helper class private to "cmcmd.cxx" to contain the implementation.
Update the link logic to use the intermediate files directory for each
target to hold manifest and resource files before embedding into the
binary. Preserve the old behavior of placing the .manifest file next
to the binary when not linking incrementally even though it will be
embedded.
Create target property WINDOWS_EXPORT_ALL_SYMBOLS to automatically
generate a module definition file from MS-compatible .obj files and give
it to the linker in order to export all symbols from the .dll part of a
SHARED library.
Add an internal "cmake -E __run_iwyu" mode to wrap the compiler call.
Run a given include-what-you-use command line with the compiler options
and report a warning if it finds anything. Then run the real compiler.

They are maintained as containing the same content as the 'home'
directories, but they are never read from.
Fix some comments and help strings which confused the two by
name. They actually mean what is called CMAKE_SOURCE_DIR in
cmake code.
Extend the RunSingleCommand signature to capture stdout and stderr
separately. Allow both to be captured to the same std::string
to preserve existing behavior. Update all call sites to do this
so that this refactoring does not introduce functional changes.
Port some existing cmJoin to use it.
cmJoin is cumbersome to use in cases where the objective is to
somehow 'quote' each item and then join it with a separator. In that
case, the joiner string is harder to read and reason about. cmWrap
aims to solve that.
Provide an overload taking char wrappers to simplify the case
of surrounding every element in quotes without needing to escape
the quote character.
Replace use of separate "cmake -E cmake_progress_report" and "cmake -E
cmake_echo_color" commands to report the progress and message portions
of build output lines with --progress-* options to the latter to print
everything with a single command. The line buffering of the stdout FILE
stream should cause the whole line to be printed with one atomic write.
This will avoid inter-mixing of line-wise messages from different
processes during a parallel build.
Read file names from the lines of a specified file. Reject input lines
starting in '-' to leave room for option parsing to be added later. Add
just '--add-file=' now to allow files starting in '-' to be specified.
Add an option to set the mtime of entries in a tarball so that one can
create a tarball with a consistent content hash (e.g. MD5) for a given
set of files regardless of their current timestamps on disk. This will
be useful for submission of tarballs to CDash, which tracks content
hashes to avoid duplication.

Use the clang RemoveCStrCalls tool to automatically migrate the
code. This was only run on linux, so does not have any positive or
negative effect on other platforms.
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.
The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
The logic added by commit ffc0b5e4 (Overwrite the symlink if it already
exists, 2007-02-15) does not recognize and remove existing broken links
before replacing them. Improve the logic to remove any existing
destination file or link (but not directory). On failure, report an
error message explaining why the existing path could not be removed or
the new one could not be created.
Add a RunCMake.CommandLine test to cover 'cmake -E' cases. Start with
test cases covering 'cmake -E create_symlink' behavior on UNIX platforms.
On posix platforms return values are limited to a range from 0 to 255.
Cross compiling/linking with MSVC on linux/wine leads to a
misinterpretation of the return value 1090650113 of mt.exe.
