I've got LNK2019 and LNK2001 from including and linking library I don't know why :(, but the vs2010.sln file works fine

[AndreiB200]

I've loaded and installed bullet3 through "vcpkg" and put the files from each folder as it should "lib" to Linker, "include" folder to Additional include folders etc... But I don't know exactly what I've done I am feeling too dumb because the "build3->vs2010" folder works perfectly fine from building from ".bat" files. I want to start to use it in another project but I don't understand if the Included files and also the .lib are integrated why is not working, in the .sln file and for each .exe file it was only src included and that was it, can someone explain what I did wrong ? The errors appears only from building.
