Fabrice Fontaine efd91329ba CMakeLists: add BUILD_{SHARED,STATIC}_LIBS options 
Add BUILD_SHARED_LIBS and BUILD_STATIC_LIBS options to allow the user
to enable/disable building of shared and static library

This is especially useful when cross-compiling as some toolchains are
not always able to build a shared or a static library
