libh2o does not require libuv, it has its own event loop. libuv is optional.

Then their FAQ needs to be updated:

To build H2O as a library you will need to install the following dependencies:

libuv version 1.0 or above OpenSSL version 1.0.2 or above

As I understand it, regular h2o doesn't require libuv but libh2o does.

The H2O build produces libh2o and libh2o-evloop. The latter doesn't depend on libuv.
