"SetPaths.cmake" (removed) - resolves absolute paths in
"zint-targets.cmake", ticket #318, props John Alexander;
also remove "FindZint.cmake" install as not best practice
(Daniel Pfeifer “Effective CMake"), but retain in tree for now;
also remove APPLE stuff re UNIVERSAL build, obsolete, and
setting of CMAKE_OSX_SYSROOT, seems unnecessary
Either shared or static (or both) libraries can be built now.
Executables (zint and zint-qt) are linked with the static library if the shared
library it not built.
The ```configuration``` is required by the visual studio generator to determine
whether to use a Debug or a Release setup (or a user customized one). It's
required by whatever uses that generator rather then just the GUI code.
Add instructions for the Visual Studio Project File generator to the README
and enable the test on Windows.
