"\n"
"A \"debug\", \"optimized\", or \"general\" keyword indicates that "
"the library immediately following it is to be used only for the "
"corresponding build configuration. "
"The \"debug\" keyword corresponds to the Debug configuration "
"(or to configurations named in the DEBUG_CONFIGURATIONS global "
"property if it is set). "
"The \"optimized\" keyword corresponds to all other configurations. "
"The \"general\" keyword corresponds to all configurations, and is "
"purely optional (assumed if omitted). "
"Higher granularity may be achieved for per-configuration rules "
"by creating and linking to IMPORTED library targets. "
"See the IMPORTED mode of the add_library command for more "
"information. "

"set of transitive link dependencies for a target."

"the LINK_INTERFACE_LIBRARIES_DEBUG property (or to the properties "
"corresponding to configurations listed in the DEBUG_CONFIGURATIONS "
"global property if it is set). "
"Libraries specified as \"optimized\" are appended to the "
"the LINK_INTERFACE_LIBRARIES property. "
"Libraries specified as \"general\" (or without any keyword) are "
"treated as if specified for both \"debug\" and \"optimized\"."
