# - Add a target for files that just need to be copied
#
# include(FileCopyTargets)
# add_file_copy_target(<target_name> <directory to copy to> <filename> [<filename>...])
# Creates a custom target that copies the files to a directory, if needed.
# Relative paths for the destination directory are considered with
# with respect to CMAKE_CURRENT_BINARY_DIR
# You can use this target in all the usual ways, including
# add_dependencies(some_other_target this_target) to specify that another
# target depends on this.
#
# install_file_copy_target(<target_name> [arguments to INSTALL(PROGRAMS ...) ])
# Works just the same as INSTALL(PROGRAMS ...) because it wraps it to install
# the files you specified in add_file_copy_target
#
#
# Requires CMake 2.6 or newer (uses the 'function' command)
