[CMake] Get linker flags / include directories for a library target

[Bo Zhou]

All the flags/options in the CMake they could be considered as a list.

So it's much more easier to handle it as this

set(WIN_DEFINITIONS -DNOMINMAX)


Remember the list is the object, so we could construct the new list for the
specific target.

Then to the specific target, just use the 3 commands.

target_compile_options()

target_include_directories()
target_link_libraries()


We use this method to organize the cross-platform with library and
executable without any problem, and super easy to control and manage.

Thanks.
