zlib is also minimal. You really don't want to do this.
WARNING
=======
Libpng 1.6.x does not use the default run-time library when building static
library builds of libpng; instead of the shared DLL runtime it uses a static
runtime. If you need to change this make sure to change the setting on all the
relevant projects:
libpng
zlib
all the test programs
The runtime library settings for each build are as follows:
Release Debug
DLL /MD /MDd
Library /MT /MTd
NOTICE that libpng 1.5.x erroneously used /MD for Debug DLL builds; if you used
the debug builds in your app and you changed your app to use /MD you will need
to change it back to /MDd for libpng 1.6.0 and later.
The Visual Studio 2010 defaults for a Win32 DLL or Static Library project are
as follows:
Release Debug
DLL /MD /MDd
Static Library /MD /MDd
