The behaviour of double specified keywords is rather undefined or at
least not clearly documented. This change introduces a strict check and
emits a warning in case a keyword has been specified more than once.
Implement a native `cmake_parse_arguments` command that is fully
compatible with the documented behaviour of the previous implementation.
Leave the CMakeParseArguments module empty but existing for
compatibility.
CMake assumes that a SHARED library compiled on Windows will export a LIB file.
This is not actually the case on Visual C++ if the library does not export any
symbols, and causes incremental builds to break if the user specifies SHARED
anyway. (Users should use MODULE libraries instead.)
Set policy CMP0065 to the value used in the calling project.
Set the the value of CMAKE_ENABLE_EXPORTS if set in the calling
project to initialize the target property appropriately.
Add documentation and tests for the existing
CTEST_CUSTOM_MAXIMUM_PASSED_TEST_OUTPUT_SIZE
CTEST_CUSTOM_MAXIMUM_FAILED_TEST_OUTPUT_SIZE
CTest variables.
When more than one value is given to the NAMES option this command by
default will consider one name at a time and search every directory for
it. Add a NAMES_PER_DIR option to tell this command to consider one
directory at a time and search for all names in it.
In the get_filename_component command, add a new BASE_DIR parameter to
use with the ABSOLUTE and REALPATH options. This will be used when
finding an absolute path from a relative path.
if(TEST TestNameThatExists) will return true if a test with the name
TestNameThatExists has been added with add_test. The syntax is similar
to if(TARGET TargetName). Since use of "TEST" as an argument to if()
could previously be interpreted as a non-keyword argument, add policy
CMP0064 to treat it as a keyword as NEW behavior.
Drop the partial documentation of properties from the command
documentation and reference the main properties manual instead.
Otherwise readers may not realize there are many more properties.
Add a TestLoad setting to CTest that can be set via a new --test-load
command-line option, CTEST_TEST_LOAD variable, or TEST_LOAD option to
the ctest_test command. Teach cmCTestMultiProcessHandler to measure
the CPU load and avoid starting tests that may take more than the
spare load currently available. The expression
<current_load> + <test_processors> <= <max-load>
must be true to start a new test.

The most likely documentation page a project author will read in
response to a policy warning is the page for the policy itself.
Add to every policy documentation page a note explicitly stating
that the OLD behavior is deprecated. Also mention this in the
cmake_policy() command documentation that explains how to set a
policy to OLD.

When documenting in the COMMAND option how to reference an executable,
we previously only explicitly covered how to do it for argv[0] and left
it to the reader to follow the reference to the generator expressions
manual. Add explicit mention of the TARGET_FILE genex in this
documentation since it will be a commonly used generator expression in
this context.
CMake-generated targets are not supported by add_dependencies. State
this explicitly and use 'install' as an example since this may be
commonly attempted.
