C++ Visual Studio: linking using pragma comment

Question

I came across a piece of code which uses #pragma comment(lib, \"libraryname\").

Why this type of usage as opposed to just linking the library from the properties men

Answer 1

Classic example - linking against different versions of the library:

#if CURRENT_VERSION >= 10
     #pragma comment(lib, "thirdPartyLibV2.0.lib")
#else //version < 10
     #pragma comment(lib, "thirdPartyLibV1.0.lib")
#endif
