Fix placing of shared libraries in Windows

[pattacini]

This PR fixes #784.

@sgiraz narrowed down the reason why part of the libraries was ok and part not. See below.

I've also reinstated the test stage of the CI on Windows.

After a quick comparison between commit 87cd0a1 and commit b6e0f7b I found the difference that caused the "fix".

In particular in src/libraries/icubmod/embObjLib/CMakeLists.txt we have the following difference:

- add_library(${PROJECT_NAME} SHARED ${embobj_source} ${embobj_header})
+ add_library(${PROJECT_NAME} ${embobj_source} ${embobj_header})

As we can see, the SHARED keyword has been removed in b6e0f7b.
