Daniel Pfeifer d6877e6c40 Don't include CMakeParseArguments
The cmake_parse_arguments command is builtin with version 3.5.
The CMakeParseArguments module is empty and exists for backwards
compatibility with CMake 3.4 and lower.

Remove the includes of CMakeParseArguments from CMake's modules.
The modules are always used with the current version of CMake.

Leave the includes in the tests, as the tests may be run with an older
version of CMake.

# CTestCoverageCollectGCOV
# ------------------------
#
# This module provides the ``ctest_coverage_collect_gcov`` function.
#
# This function runs gcov on all .gcda files found in the binary tree
# and packages the resulting .gcov files into a tar file.
# This tarball also contains the following:
#
# * *data.json* defines the source and build directories for use by CDash.
# * *Labels.json* indicates any :prop_sf:`LABELS` that have been set on the
# source files.
# * The *uncovered* directory holds any uncovered files found by
# :variable:`CTEST_EXTRA_COVERAGE_GLOB`.
#
# After generating this tar file, it can be sent to CDash for display with the
# :command:`ctest_submit(CDASH_UPLOAD)` command.
#
# .. command:: cdash_coverage_collect_gcov
#
# ::
#
# ctest_coverage_collect_gcov(TARBALL <tarfile>
# [SOURCE <source_dir>][BUILD <build_dir>]
# [GCOV_COMMAND <gcov_command>]
# [GCOV_OPTIONS <options>...]
# )
#
# Run gcov and package a tar file for CDash. The options are:
#
# ``TARBALL <tarfile>``
# Specify the location of the ``.tar`` file to be created for later
# upload to CDash. Relative paths will be interpreted with respect
# to the top-level build directory.
#
# ``SOURCE <source_dir>``
# Specify the top-level source directory for the build.
# Default is the value of :variable:`CTEST_SOURCE_DIRECTORY`.
#
# ``BUILD <build_dir>``
# Specify the top-level build directory for the build.
# Default is the value of :variable:`CTEST_BINARY_DIRECTORY`.
#
# ``GCOV_COMMAND <gcov_command>``
# Specify the full path to the ``gcov`` command on the machine.
# Default is the value of :variable:`CTEST_COVERAGE_COMMAND`.
#
# ``GCOV_OPTIONS <options>...``
# Specify options to be passed to gcov. The ``gcov`` command
# is run as ``gcov <options>... -o <gcov-dir> <file>.gcda``.
# If not specified, the default option is just ``-b``.
#
# ``GLOB``
# Recursively search for .gcda files in build_dir rather than
# determining search locations by reading TargetDirectories.txt.
#
# ``DELETE``
# Delete coverage files after they've been packaged into the .tar.
#
# ``QUIET``
# Suppress non-error messages that otherwise would have been
# printed out by this function.
