Add option to build library as a shared object.

I see currently library is being built as a static library. That makes every project that uses this library inject the code inside their program. Instead it can be built as a dynamic library (.so on linux and .dll on windows) and link dynamically on the runtime. It will reduce size of the result binaries and will get an option to users to update ittapi library without updating application (if the ABI is compatible).

My question is if it possible to add shared target to the build? It should be as easy as removing STATIC keyword from add_library and then it can be controlled with BUILD_SHARED_LIBS argument. Or there is a reason why it can't be loaded as a shared library?

In short, ittapi being a static library is a design decision and converting it to a shared library would break a lot of things. ittapi has to distinguish the dynamic library it was being called from in some cases and the simplest way was to do it was to link statically to each of the instrumented exes/dlls.
