xed undeclared error on make

[nba28]

Hey!

I'm getting a few errors,

1. for some reason my compiler would whine about #include missing from a bunch of files, but i fixed that manually.
2. after fixing the include statements missing, seems like there's only one error left. when i tried make again i get this: /Users/[user]/Downloads/86x64/src/core/instruction.cc:241:15: error: use of undeclared identifier 'xed_patch_relbr'
   241 | if (!xed_patch_relbr(&xedd, &*instbuf.begin(), enc)) {
   | ^
   1 error generated.
   make[2]: *** [src/core/CMakeFiles/core_objs.dir/instruction.cc.o] Error 1
   make[1]: *** [src/core/CMakeFiles/core_objs.dir/all] Error 2
   make: *** [all] Error 2

Could you please help me fix this?
Thanks in advance!
