You need to compile a software with the SDK to be able to host native (.so;
_not_ .dll) VST plug-ins. JOST's binaries on the site are already
precompiled with it (the author just does not include the header(s) in the
source tarballs). IIRC, Qtractor can also be compiled with the SDK and it
can host native plug-ins, besides the commercial options like Renoise and
energyXT.
