The first instinct of a lot of users is to use file(GLOB) to assemble
lists of sources. Add a warning to the help text stating that it should
not be used for this purpose and briefly explain why.

Improve FILE(DOWNLOAD ...):
- Add percent complete progress output to the FILE DOWNLOAD
command. This progress output is off by default to
preserve existing behavior. To turn it on, pass
SHOW_PROGRESS as an argument.
- Add EXPECTED_MD5 argument. Verify that the downloaded
file has the expected md5 sum after download is complete.
- Add documentation for SHOW_PROGRESS and EXPECTED_MD5.
When the destination file exists already and has the
expected md5 sum, then do not bother re-downloading
the file. ("Short circuit" return.)
Also, add a test that checks for the status output
indicating that the short circuit behavior is actually
occurring. Use a binary file for the test so that the
md5 sum is guaranteed to be the same on all platforms
regardless of "shifting text file line ending" issues.
Improve ExternalProject:
- Add argument URL_MD5.
- Add verify step that compares md5 sum of .tar.gz file
before extracting it.
- Add md5 check to download step, too, to prevent
unnecessary downloads.
- Emit a warning message when a file is not verified.
Indicate that the file may be corrupt or that no
checksum was specified.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
The file(INSTALL) command has long been undocumented and used only to
implement install() scripts. We now document it and provide a similar
file(COPY) signature which is useful in general-purpose scripts. It
provides the capabilities of install(DIRECTORY) and install(FILES) but
operates immediately instead of contributing to install scripts.
The undocumented file(INSTALL) is implemented by a cmFileInstaller class
inside cmFileCommand. This refactors the class to split out code not
specific to installation into a cmFileCopier base class.
This creates a single cmFileInstaller method to dispatch installation of
symlinks, directories, and files. The change removes duplicate tests of
input file type and makes the decision more consistent.
- CMake 1.8 and below did not do the check but could get in
infinite loops due to the local generate step.
- CMake 2.0 added the check but failed to perform it in directories
with no targets (see bug #678).
- CMake 2.2 removed the local generate which fixed the problem but
did not remove the check.
- Between CMake 2.4 and 2.6.0rc6 the check was fixed to work even
when no targets appear in a directory (see bug #6923).
- Bottom line: the check is no longer needed.
- If new RPATH is empty then remove the entry completely
- Preserve file modification time so installation is not repeated
- If installed file already exists remove it if its RPATH
does not match that expected
- Add cmSystemTools::ChangeRPath method
- Add undocumented file(CHRPATH) command
- When installing use file(CHRPATH) to change the rpath
instead of relinking
- Remove CMAKE_CHRPATH lookup from CMakeFindBinUtils
- Remove CMAKE_USE_CHRPATH option since this should
always work
offset can be specified where the reading starts, and using HEX the data can
be converted into a hex string, so binary data can be compared with text
functions
-add docs for LIMIT, OFFSET and HEX

conversion of hex and srec files to binary.
Without this automatic conversion, everywhere where a compiled file is parsed for strings the
a file(HEX2BIN somefile binfile) command has to be added otherwise it will
not work for these compilers. I tried this with DetermineCompiler and
CheckTypeSize and nobody will do this except the users who work with such
compilers. For them it will break if they don't add this conversion command
in all these places.
If FILE(STRINGS) is used with a text file, it
will in most cases still work as expected, since it will only convert hex
and srec files. If a user actually wants to get text out of hex files, he
knows what he's doing and will see the hint in the documentation.
Anyway, it should work without having to create a temporary file, will work
on this later.

-add a RESULT_VARIABLE to INCLUDE()
-add CMAKE_TOOLCHAIN_FILE for specifiying your (potentially crosscompiling) toolchain
-have TRY_RUN() complain if you try to use it in crosscompiling mode (which were compiled but cannot run on this system)
-use CMAKE_EXECUTABLE_SUFFIX in TRY_RUN(), probably TRY_RUN won't be able to
run the executables if they have a different suffix because they are
probably crosscompiled, but nevertheless it should be able to find them
-make several cmake variables presettable by the user: CMAKE_C/CXX_COMPILER, CMAKE_C/CXX_OUTPUT_EXTENSION, CMAKE_SYSTEM_NAME, CMAKE_SYSTEM_INFO_FILE
-support prefix for GNU toolchains (arm-elf-gcc, arm-elf-ar, arm-elf-strip etc.)
-move ranlib on OSX from the file command to a command in executed in cmake_install.cmake
-add support for stripping during install in cmake_install.cmake
-split out cl.cmake from Windows-cl.cmake, first (very incomplete) step to support MS crosscompiling tools
-remove stdio.h from the simple C program which checks if the compiler works, since this may not exist for some embedded platforms
-create a new CMakeFindBinUtils.cmake which collects the search fro ar, ranlib, strip, ld, link, install_name_tool and other tools like these
-add support for CMAKE_FIND_ROOT_PATH for all FIND_XXX commands, which is a
list of directories which will be prepended to all search directories, right
now as a cmake variable, turning it into a global cmake property may need
some more work
-remove cmTestTestHandler::TryExecutable(), it's unused
-split cmFileCommand::HandleInstall() into slightly smaller functions
