The --trace option is helpful, but sometimes, what you're looking for is
deep under many layers of function calls and figuring out what instance
of the function call you're looking at is tedious to determine (usually
involving patching and message()). Instead, add a --trace-expand option
to trace while expanding commands into what CMake actually sees.
The VS >= 10 generators need to parse the .sln file from the build
directory to locate targets in subdirectories. This occurs after we
change the working directory to the build tree. If a relative directory
other than "." was given then we would change to it and also refer to
the .sln file location with it. Fix this by converting the build tree
to a full path always. This will also give a more informative error
message when the directory does not exist.
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.

Port most CMakeTestBadCommandLines test cases to RunCMake.CommandLine
and drop the former test. Add validation of expected results, which was
not done by the old test.
Otherwise an #include directive on the first line of a source file is
ignored if the file contains a Byte-Order-Mark.

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.

Expect tests to specify stderr content if it is present.
Fix the CMP0019 test, which has only been testing the WARN status
until now. Specify in the CommandLine and FPHSA tests that content
is at least one character.
Set policies in the Language and CheckModules tests, which have empty
test output, modulo unrelated policies on some platforms.
In the case of:
-DCACHE_VARS=-DEXTERNAL_PROJECT_CMAKE_ARG:BOOL=TRUE
the variable is parsed out as:
CACHE_VARS=-DEXTERNAL_PROJECT_CMAKE_ARG
because the parser allows '=' in the variable name. Disallow such a name
on the command line.
Extend the cmake command-line interface to support
cmake -E env [--unset=NAME]... [NAME=VALUE]... COMMAND [ARG]...
This will be useful to run processes with modified environments
without using a shell or a full "cmake -P" script to wrap it.
Extend the RunCMake.CommandLine test to cover success and failure cases.

If we fail to create the generator named by CMAKE_GENERATOR, exit
with an error message instead of crashing. While at it, fix the
wording of the error message when CMAKE_GENERATOR is not set.
Extend the RunCMake.CommandLine test with cases covering the
"cmake --build" option when the named directory does not provide
a CMakeCache.txt with a valid CMAKE_GENERATOR.
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.
