### compile WITH_OPENSSL
Enable SSL in libhv is so easy, just only two apis:
```
// init ssl_ctx, see ssl/hssl.h
hssl_ctx_t hssl_ctx_init(hssl_ctx_init_param_t* param);

// enable ssl, see event/hloop.h
int hio_enable_ssl(hio_t* io);
```

https is the best example.
```
sudo apt install openssl libssl-dev # ubuntu
./configure --with-openssl
make clean && make
bin/httpd -s restart -d
bin/curl -v http://localhost:8080
bin/curl -v https://localhost:8443
```

### compile WITH_CURL
```
./configure --with-curl
make clean && make
bin/httpd -s restart -d
bin/curl -v http://localhost:8080
```

### compile WITH_NGHTTP2
```
sudo apt install libnghttp2-dev # ubuntu
./configure --with-nghttp2
make clean && make
bin/httpd -s restart -d
bin/curl -v http://localhost:8080 --http2
```

### compile WITH_KCP
```
./configure --with-kcp
make clean && make
```
