Hi Adrian Costin, i used other config in visual studio 2015,
i seed you use the libtins.lib, this it the static config for libtins, but, are you compile libtins in your pc?.
in these case i proposed, at you try the next config, first, your package wpcad is the developer this ok, in my experience: the best sitie for unzip the develop wpcal is C: Disk,
your can intented a path with of next: C:\mylibraryc++\,
if you unzip ok, hands on.
- in yout visual studio, you see same at:

- clik rigth in the project, go to propierties:

- in the window property,(the recent open window) go to "VC++
directories",and selected

- in the opcions for "vc++ directories" selected "include", and you include path of C:\mylibraryc++\WpdPack_4_1_2\include


- and a posible result in my case it is:

- in the "vc++ directories" selected, go to "library directories" and repeat, but need change the folder, at the folder the Lib, see picture, in the red rectangle:

- ok, were you have selected "vc++ directories", change the option to "linker" and go to "input" >> aditional depends and add wpcap.lib see picture

- in this moment your app build, but generate two problems the first its the crono.h this a warning, in my develop,this it no generate nothing problem, the second is the fault, lack, need,etc. of "WIN_32"prefix, in these case, you go to "propierties", and the window propierties go to "C/C++" and "Procesor" >> "Preporcessor
Definitions", add WIN32 see picture

- Ok, in this moment your app build and compile, with alone warning of the crono.h, the next is build libtins, i explain the two forms for build. with visual and the cmake GUI and cmake cmd.
i hope this is most help you. i want wait for you response and go to the compile build libtins, happu day. :)
