Subversion package doesn't support URL, lacking serf lib?

Hello!

I installed Subversion-client and Subversion-libs on my OpenWRT. When I try to checkout using svn checkout https://URL I get error message svn: E170000: Unrecognized URL scheme for 'https://URL'

Googling about it I found https://serverfault.com/questions/522646/svn-e170000-unrecognized-url-scheme-for-httpxxxx
It explains that Subversion must be compiled with serf to user URLs.

I searched serf on opkg and on luci software page and couldn't find anything.

Could anybody confirm that OpenWRT's Subversion package doesn't support URLs, and if there's any way to make it work?

I'm not used to compile software on linux but I might try it.
