+# MODULE:   DownloadProject
+#
+# PROVIDES:
+#   download_project( PROJ projectName
+#                    [PREFIX prefixDir]
+#                    [DOWNLOAD_DIR downloadDir]
+#                    [SOURCE_DIR srcDir]
+#                    [BINARY_DIR binDir]
+#                    [QUIET]
+#                    ...
+#   )
+#
+#       Provides the ability to download and unpack a tarball, zip file, git repository,
+#       etc. at configure time (i.e. when the cmake command is run). How the downloaded
+#       and unpacked contents are used is up to the caller, but the motivating case is
+#       to download source code which can then be included directly in the build with
+#       add_subdirectory() after the call to download_project(). Source and build
+#       directories are set up with this in mind.
+#
+#       The PROJ argument is required. The projectName value will be used to construct
+#       the following variables upon exit (obviously replace projectName with its actual
+#       value):
+#
+#           projectName_SOURCE_DIR
+#           projectName_BINARY_DIR
+#
+#       The SOURCE_DIR and BINARY_DIR arguments are optional and would not typically
+#       need to be provided. They can be specified if you want the downloaded source
+#       and build directories to be located in a specific place. The contents of
+#       projectName_SOURCE_DIR and projectName_BINARY_DIR will be populated with the
+#       locations used whether you provide SOURCE_DIR/BINARY_DIR or not.
+#
+#       The DOWNLOAD_DIR argument does not normally need to be set. It controls the
+#       location of the temporary CMake build used to perform the download.
+#
+#       The PREFIX argument can be provided to change the base location of the default
+#       values of DOWNLOAD_DIR, SOURCE_DIR and BINARY_DIR. If all of those three arguments
+#       are provided, then PREFIX will have no effect. The default value for PREFIX is
+#       CMAKE_BINARY_DIR.
+#
+#       The QUIET option can be given if you do not want to show the output associated
+#       with downloading the specified project.
+#
+#       In addition to the above, any other options are passed through unmodified to
+#       ExternalProject_Add() to perform the actual download, patch and update steps.
+#       The following ExternalProject_Add() options are explicitly prohibited (they
+#       are reserved for use by the download_project() command):
+#
+#           CONFIGURE_COMMAND
+#           BUILD_COMMAND
+#           INSTALL_COMMAND
+#           TEST_COMMAND
+#
+#       Only those ExternalProject_Add() arguments which relate to downloading, patching
+#       and updating of the project sources are intended to be used. Also note that at
+#       least one set of download-related arguments are required.
+#
+#       If using CMake 3.2 or later, the UPDATE_DISCONNECTED option can be used to
+#       prevent a check at the remote end for changes every time CMake is run
+#       after the first successful download. See the documentation of the ExternalProject
+#       module for more information. It is likely you will want to use this option if it
+#       is available to you. Note, however, that the ExternalProject implementation contains
+#       bugs which result in incorrect handling of the UPDATE_DISCONNECTED option when
+#       using the URL download method or when specifying a SOURCE_DIR with no download
+#       method. Fixes for these have been created, the last of which is scheduled for
+#       inclusion in CMake 3.8.0. Details can be found here:
+#
+#           https://gitlab.kitware.com/cmake/cmake/commit/bdca68388bd57f8302d3c1d83d691034b7ffa70c
+#           https://gitlab.kitware.com/cmake/cmake/issues/16428
+#
+#       If you experience build errors related to the update step, consider avoiding
+#       the use of UPDATE_DISCONNECTED.
+#
+# EXAMPLE USAGE:
+#
+#   include(DownloadProject)
+#   download_project(PROJ                googletest
