Undefined symbols for architecture x86_64

[fecub]

I got this error during compilation, any idea how to solve this problem?

MyMachine:
MacOS Catalina 10.15.6, Darwin Kernel Version 19.6.0

Undefined symbols for architecture x86_64:
  "LiveWindow::qInitResources_livewindow()", referenced from:
      LiveWindow::loadLiveWindow() in livewindow.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [libcom_machinekoder_live_plugin.dylib] Error 1
make: *** [sub-lib-make_first] Error 2

P.S: I compiled before on a linux machine without problems, but got problems on macOS.
