Possibly useful addition:

The file 8bit/CMakeFiles/cli.dir/linklibs.rsp contains a line

+----
  libx265.a -Wl,-Bstatic -lx265_main10.a x265_main12 -Wl,-Bdynamic  
-lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid  
-lcomdlg32 -ladvapi32
+----

but I guess it should contain instead

+----
  libx265.a -Wl,-Bstatic libx265_main10.a libx265_main12.a -Wl,-Bdynamic  
-lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid  
-lcomdlg32 -ladvapi32
+----

Manually patching this file, I got a multilib EXE which does at least  
report version strings as expected; now it's your turn to discover how  
cmake can build this file correctly.

Fun and success!
