I have decided to try and build it all with -DENABLE_STATIC=ON, but I am
getting lots of warnings about inconsistent DLL linkage

I am clearly doing something wrong in the build here, I'm just not sure
what.

I am using this command:-

C:\taglib\taglib-1.8>cmake" -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release
-DENABLE_STATIC=ON -DZLIB_INCLUDE_DIR=C:\taglib\zlib-1.2.8\
-DZLIB_LIBRARY=C:\taglib\zlib-1.2.8\zlibstatic.lib .
 then nmake clean and nmake

I get the feeling this is something simple I am missing. Can you help?
