Use this variable to specify a list of labels that will be reported to
CDash as subprojects.

Currently, CTest will not initialize any submodules within the already
checked out source tree. Add an option to do so. The use case for not
doing so is that some submodules may not be necessary for the current
test and keeping network usage down may be important.

The compiler version reported since commit v2.8.2~1018 (CTest-side
support for compiler name and compiler version, 2009-10-12) only
reported the version of the compiler used to build CMake, and only
if it defined "_COMPILER_VERSION".  Instead use the version of
the compiler used to build the project CTest is testing.

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.

Sanitizers receive options through their environment variable; support
user-specified options here.

This allows ctest_update to get the current version without actually
changing the repository.  This is useful when using Jenkins or an
external project to update the source to a specific version, but you
still want the current version to show up in CDash.

Before this commit, you would have to run ctest -S mode to get
MemoryCheckType to work. This is because CMAKE_COMMAND was not set.
The fix is to use cmSystemTools::GetCMakeCommand instead.

Teach the ctest_update implementation to use the p4 command-line
client to perform updates and extract the list of changes.

Add a CTest.UpdateP4 test like those that exist already for the other
version control tools.  Make the test available when p4 and the p4d
server are found.  During the test launch p4d in the background to
serve a repository from the test directory.  Then direct the client
toward this server for the duration of the test.

While at it, add SVNOptions/CTEST_SVN_OPTIONS configuration settings to
add options to all svn invocations instead of just "svn update".

COVERAGE_EXTRA_FLAGS is a space separated value of extra flags
that will be passed to gcov when ctest's coverage handler invokes
gcov to do coverage analysis.

Map to CoverageExtraFlags in the CTest ini file. Use default value
of "-l" to match the coverage handler's earlier behavior from ctest
2.8.4 and earlier. The fix for related issue #11717 had added a " -p"
which was the cause of both #12415 and #12490. Here, we revert that
change to the default value, so -p is no longer there by default.
The people that care to add -p may do so in their own build trees
by appending " -p" to the new cache variable COVERAGE_EXTRA_FLAGS.

Define CTest configuration variable CTEST_GIT_UPDATE_CUSTOM to set a
custom command line for updating Git-managed source trees.

Allow the user to set the CMake variable CTEST_COST_DATA_FILE, which will be used to store the cost data from test runs.  If not set, defaults to the original location in the build tree Testing/Temporary dir.

Moved call to cache CDash version information to cmCTest::initialize.  Also added a 3 second timeout when requesting the version from the server.  Added an option to the CTestConfiguration that will be used to determine whether to query the version information at all.  (Behavior for this setting is not yet defined.)  Updated CMake's local CDash version setting to 1.6.

Added support for CTest awareness of the CDash version.  This will help forward compatibility for both tools.  Note that this changeset effectively makes the default to disable output compression.  Now, to enable output compression, the CDASH_CTEST_VERSION must be explicity set to >= 1.6.  Automated detection of the CDash version is the next step.

Fix issue #2336 - honor the -C arg to ctest. Honor it for all stages of running -D dashboards from the command line and running ctest_configure, ctest_build and ctest_test commands in -S scripts. Also, allow a script to change it by setting the CTEST_CONFIGURATION_TYPE variable: allows for multiple configuration build/test cycles within one script. Add a new signature for the cmake command build_command that accepts CONFIGURATION as one argument. The original build_command signature is still there, but now marked as deprecated in the documentation. Of course... also add CTestConfig tests to verify that -C is honored for -D dashboards and -S scripts.

CTest-side support for compiler name and compiler version information.  Requires CDash update to show on CDash.

Fixed ctest output where max test index is not the same width as the total number of tests.  Also some preliminary changes for batching ctest jobs

This defines a new CTest configuration variable CTEST_USE_LAUNCHERS.
When set to true it puts 'ctest --launch' in RULE_LAUNCH_* properties
and enables the CTest configuration option 'UseLaunchers'.  Currently
this works only for Makefile generators.
