your engine runs fine in CuteChess (GUI) but the move list doesn't show the eval values next to each (best)move : all eval values are "0.00" .. however, in the evaluation pane the eval values ARE shown at each depth ..

i guess you never mentioned and this can be solved easily.
btw. i tried v1.1 and v1.2, both have the same issue.

while compiling your v1.1 source on Linux, i encounter this error in the files /src/nnue.cpp and /src/nnue/accumulator.hpp :

error: no member named 'memcpy' in namespace 'std'

the function memcpy is defined in header <cstring>, so i had to add #include <cstring> on top of those files.
this way i was able to compile Jet v1.1 and it runs fine in CuteChess !

Note: besides that, i had (only) 1 warning in src/nnue.cpp :

variable 'bytesRead' set but not used [-Wunused-but-set-variable]
uint64_t bytesRead = 0;
