# 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:
#
