Bug#908124: libh2o-evloop-dev: Depends on libwslay to link but doesn't say so in pkg-config file

[Chris Hofstaedtler]

Package: libh2o-evloop-dev
Version: 2.2.5+dfsg1-6
Severity: important

Hi,

the libh2o-evloop shared library needs symbols from libwslay, but the
pkg-config file does not specify this. As such, downstream users of
libh2o-evloop need to manually add -lwslay to their command lines.

Please add -lwslay to libh2o-evloop.pc.

Errors etc:
/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/libh2o-evloop.so: 
undefined reference to `wslay_event_want_read’.
...

Thanks,
Chris
