# 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
# GIT_REPOSITORY https://github.com/google/googletest.git
# GIT_TAG master
# UPDATE_DISCONNECTED 1
# QUIET

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
