# - 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)
