Compile sf in windows with liblwgeom

Dear list, I have a MULTIPOLYGON geometry set where the rings are in the wrong direction and would like to correct that with *st_make_valid*. As I'm in Windows and use the binary version of the *sf* package it gives me the error:
sp2 = st_make_valid(sp1)
Error in CPL_make_valid(x) : st_make_valid requires compilation against liblwgeom Is there a series of steps I can follow for compiling *sf* in Windows linked to liblwgeom?
No, and I also don't think that st_make_valid does this. Converting to sp and back, like st_as_sf(as(sp1, "Spatial")) might do the trick, though.
Thanks [[alternative HTML version deleted]]
