General understanding building sources to windows libraries

[Ijaja]

Hello,

i am very new to development and for now i am just interested in understanding how the module sources correlated to the built plugin dlls.
For example i am looking for the source file mad.c. There is the Makefile.am which indicates the built module is libmad_plugin. But i cannot find
a libmad-plugin.dll. So at any place must be the information which dll is finally built from the source. Where can i find it?
Thank you very much in advance for any help,


best regards,

Daniel

Another thing is the other way round:

What are the sources for libh264_plugin.dll for example?

Thx
