We need the latest Tests/CMakeLists.txt so we can refactor all tests.

+# - Manage data files stored outside source tree
+# Use this module to unambiguously reference data files stored outside the
+# source tree and fetch them at build time from arbitrary local and remote
+# content-addressed locations.  Functions provided by this module recognize
+# arguments with the syntax "DATA{<name>}" as references to external data,
+# replace them with full paths to local copies of those data, and create build
+# rules to fetch and update the local copies.
+#
+# The DATA{} syntax is literal and the <name> is a full or relative path
+# within the source tree.  The source tree must contain either a real data
+# file at <name> or a "content link" at <name><ext> containing a hash of the
+# real file using a hash algorithm corresponding to <ext>.  For example, the
+# argument "DATA{img.png}" may be satisfied by either a real "img.png" file in
+# the current source directory or a "img.png.md5" file containing its MD5 sum.
+#
+# The 'ExternalData_Expand_Arguments' function evaluates DATA{} references
+# in its arguments and constructs a new list of arguments:
+#  ExternalData_Expand_Arguments(
+#    <target>   # Name of data management target
+#    <outVar>   # Output variable
+#    [args...]  # Input arguments, DATA{} allowed
+#    )
+# It replaces each DATA{} reference in an argument with the full path of a
+# real data file on disk that will exist after the <target> builds.
+#
+# The 'ExternalData_Add_Test' function wraps around the CMake add_test()
+# command but supports DATA{} references in its arguments:
+#  ExternalData_Add_Test(
+#    <target>   # Name of data management target
+#    ...        # Arguments of add_test(), DATA{} allowed
+#    )
+# It passes its arguments through ExternalData_Expand_Arguments and then
+# invokes add_test() using the results.
+#
+# The 'ExternalData_Add_Target' function creates a custom target to manage
+# local instances of data files stored externally:
+#  ExternalData_Add_Target(
+#    <target>   # Name of data management target
+#    )
+# It creates custom commands in the target as necessary to make data files
+# available for each DATA{} reference previously evaluated by other functions
+# provided by this module.  A list of URL templates must be provided in the
+# variable ExternalData_URL_TEMPLATES using the placeholders "%(algo)" and
+# "%(hash)" in each template.  Data fetch rules try each URL template in order
+# by substituting the hash algorithm name for "%(algo)" and the hash value for
+# "%(hash)".
+#
+# The following hash algorithms are supported:
+#    %(algo)     <ext>     Description
+#    -------     -----     -----------
+#    MD5         .md5      Message-Digest Algorithm 5, RFC 1321
+#    SHA1        .sha1     US Secure Hash Algorithm 1, RFC 3174
+#    SHA224      .sha224   US Secure Hash Algorithms, RFC 4634
+#    SHA256      .sha256   US Secure Hash Algorithms, RFC 4634
+#    SHA384      .sha384   US Secure Hash Algorithms, RFC 4634
+#    SHA512      .sha512   US Secure Hash Algorithms, RFC 4634
+# Note that the hashes are used only for unique data identification and
+# download verification.  This is not security software.
+#
+# Example usage:
+#   include(ExternalData)
+#   set(ExternalData_URL_TEMPLATES "file:///local/%(algo)/%(hash)"
+#                                  "http://data.org/%(algo)/%(hash)")
+#   ExternalData_Add_Test(MyData
+#     NAME MyTest
+#     COMMAND MyExe DATA{MyInput.png}
+#     )
+#   ExternalData_Add_Target(MyData)
+# When test "MyTest" runs the "DATA{MyInput.png}" argument will be replaced by
+# the full path to a real instance of the data file "MyInput.png" on disk.  If
+# the source tree contains a content link such as "MyInput.png.md5" then the
+# "MyData" target creates a real "MyInput.png" in the build tree.
+#
+# The DATA{} syntax can be told to fetch a file series using the form
+# "DATA{<name>,:}", where the ":" is literal.  If the source tree contains a
+# group of files or content links named like a series then a reference to one
+# member adds rules to fetch all of them.  Although all members of a series
+# are fetched, only the file originally named by the DATA{} argument is
+# substituted for it.  The default configuration recognizes file series names
+# ending with "#.ext", "_#.ext", ".#.ext", or "-#.ext" where "#" is a sequence
+# of decimal digits and ".ext" is any single extension.  Configure it with a
+# regex that parses <number> and <suffix> parts from the end of <name>:
+#  ExternalData_SERIES_PARSE = regex of the form (<number>)(<suffix>)$
+# For more complicated cases set:
+#  ExternalData_SERIES_PARSE = regex with at least two () groups
+#  ExternalData_SERIES_PARSE_PREFIX = <prefix> regex group number, if any
+#  ExternalData_SERIES_PARSE_NUMBER = <number> regex group number
+#  ExternalData_SERIES_PARSE_SUFFIX = <suffix> regex group number
+# Configure series number matching with a regex that matches the
+# <number> part of series members named <prefix><number><suffix>:
+#  ExternalData_SERIES_MATCH = regex matching <number> in all series members
+# Note that the <suffix> of a series does not include a hash-algorithm
+# extension.
+#
+# The DATA{} syntax can alternatively match files associated with the named
+# file and contained in the same directory.  Associated files may be specified
+# by options using the syntax DATA{<name>,<opt1>,<opt2>,...}.  Each option may
+# specify one file by name or specify a regular expression to match file names
+# using the syntax REGEX:<regex>.  For example, the arguments
+#   DATA{MyData/MyInput.mhd,MyInput.img}                   # File pair
+#   DATA{MyData/MyFrames00.png,REGEX:MyFrames[0-9]+\\.png} # Series
+# will pass MyInput.mha and MyFrames00.png on the command line but ensure
+# that the associated files are present next to them.
+#
+# The DATA{} syntax may reference a directory using a trailing slash and a
+# list of associated files.  The form DATA{<name>/,<opt1>,<opt2>,...} adds
+# rules to fetch any files in the directory that match one of the associated
+# file options.  For example, the argument DATA{MyDataDir/,REGEX:.*} will pass
+# the full path to a MyDataDir directory on the command line and ensure that
+# the directory contains files corresponding to every file or content link in
+# the MyDataDir source directory.
+#
+# The variable ExternalData_LINK_CONTENT may be set to the name of a supported
+# hash algorithm to enable automatic conversion of real data files referenced
+# by the DATA{} syntax into content links.  For each such <file> a content
+# link named "<file><ext>" is created.  The original file is renamed to the
+# form ".ExternalData_<algo>_<hash>" to stage it for future transmission to
+# one of the locations in the list of URL templates (by means outside the
+# scope of this module).  The data fetch rule created for the content link
+# will use the staged object if it cannot be found using any URL template.
+#
+# The variable ExternalData_OBJECT_STORES may be set to a list of local
+# directories that store objects using the layout <dir>/%(algo)/%(hash).
+# These directories will be searched first for a needed object.  If the object
+# is not available in any store then it will be fetched remotely using the URL
+# templates and added to the first local store listed.  If no stores are
+# specified the default is a location inside the build tree.
+#
+# The variable ExternalData_SOURCE_ROOT may be set to the highest source
+# directory containing any path named by a DATA{} reference.  The default is
+# CMAKE_SOURCE_DIR.  ExternalData_SOURCE_ROOT and CMAKE_SOURCE_DIR must refer
+# to directories within a single source distribution (e.g. they come together
+# in one tarball).
+#
+# The variable ExternalData_BINARY_ROOT may be set to the directory to hold
+# the real data files named by expanded DATA{} references.  The default is
+# CMAKE_BINARY_DIR.  The directory layout will mirror that of content links
+# under ExternalData_SOURCE_ROOT.
+#
+# Variables ExternalData_TIMEOUT_INACTIVITY and ExternalData_TIMEOUT_ABSOLUTE
+# set the download inactivity and absolute timeouts, in seconds.  The defaults
+# are 60 seconds and 300 seconds, respectively.  Set either timeout to 0
+# seconds to disable enforcement.
