Hi,

This rabbit hole went quite a bit deeper than I expected. Apparently,
CMake prepends 'lib' to library names for unix like environments
(including MinGW) but not for Visual Studio. So, when building on
Windows, you get either libFLAC.dll and libogg.dll or FLAC.dll and
ogg.dll depending on what toolchain you're using. I'm not quite sure
whether this makes sense. I've tried quite a few ways to override this
behaviour, but the most obvious solutions didn't work.

Sorry, I've been trying various things for two hours today, I give up.
Perhaps someone else on this list knows the answer.

Kind regards,

Martijn van Beurden

I want the CMake-generated project file name is libogg, not ogg. I check the
CMakeLists.txt and confilgure file in flac-1.4.2, and don't find how to
change ogg project name to libogg.

Might have to figure out where cmake is installed on Windows, find the 
file Modules\Platform\Windows.cmake and edit the line
set(CMAKE_SHARED_LIBRARY_PREFIX "")          # lib
to
SET(CMAKE_SHARED_LIBRARY_PREFIX "lib")
Which will of course cause all DLL's to have the lib prefix.
Might be a different Platform file to edit too as I'm making assumptions 
and haven't actually tested, no Windows here.
