# These functions can be called to add generated files (as opposed to source files)
# to the distribution tarball
# - dist_add_configured will only add the files to the tarball. This function
# should be used for files that are generated during a cmake run (for example with configure_file)
# - dist_add_generated will add the files to the tarball and generate a dependency
# for each file to the dist target. This function should be used for all files that
# will be generated during a "make" or "ninja-build" run (for example those that are
# the result of an add_custom_command)
#
# Note that the files passed in these functions can still be in the source directory
# This depends on whether or not the source is a git worktree or not and which
# options were passed to cmake.
# To determine this, the first parameter passed to this function should
# be an indicator whether or not the files in the list are actually built
# in this configuration. At the time of this writing there is one
# cmake variable that controls this, and hence can be used here:
# BUILDING_FROM_VCS: is YES when building from a git source tree
