 * cmTargetLinkLibrariesCommand is used to specify a list of libraries to link
 * into executable(s) or shared objects. The names of the libraries
 * should be those defined by the LIBRARY(library) command(s).
 *
 * Additionally, it allows to propagate usage-requirements (including link
 * libraries) from one target into another.
