Link libraries to all targets added later.
link_libraries([item1 [item2 [...]]]
[[debug|optimized|general] <item>] ...)
Specify libraries or flags to use when linking any targets created later in
the current directory or below by commands such as
add_library(). See the
for meaning of arguments.
target_link_libraries() command should be preferred whenever
possible. Library dependencies are chained automatically, so directory-wide
specification of link libraries is rarely needed.
