Because

(1) ADD_LIBRARY() might lack the SHARED/STATIC keyword, and the user
can decide which type of library is built via the BUILD_SHARED_LIBS
variable, so an ADD_LIBRARY() command can be unalteredly used to
build a shared library as well as a static one, and

(2) on *nix, the outcome of ADD_LIBRARY(... SHARED ...) is a LIBRARY
target whereas on Windows, the DLL part is a RUNTIME target, and the
accompanying import library is an ARCHIVE target.

For these reasons, the same ADD_LIBRARY() command - i.e., the same
target - might generate different types of libraries, so there is
a need to specify the respective *_OUTPUT_DIRECTORY individually.

Michael
