See also issue #1489.

@martinmoene Thanks for this PR! It looks pretty good to me, but I have one question.

I took the "Example Usage" code from the lest github repo and attempted to build. The example doesn't build because this port installs the headers into the lest folder, so the include needs to be modified to #include <lest/lest.hpp>. I just want to confirm that this is intentional/how the library is intended to be used before merging this PR. 😄

@Codiferous Ah, good catch, I'll look into it and update/report back.

[martinmoene]

@Codiferous I changed the occurrences of #include "lest.hpp" and the like to #include "lest/lest.hpp" and tried it successfully with Visual Studio 2017. Release tag now is v1.34.1.

Argh! lest version needs updating... back in a minute...

[martinmoene]

@Codiferous ok, done.

@martinmoene I updated the hash for lest because it wasn't matching. With that change, everything looks beautiful. I'm really happy to have lest in vcpkg! 😄
