Build fails on Mac OSX Catalina (10.15)

Build on Mac OSX 10.15 fails, possibly due to changes in the framework environment:

Undefined symbols for architecture x86_64:
  "_SecTaskCopyValueForEntitlement", referenced from:
      _darwin_detach_kernel_driver in libusb-1.0.a(darwin_usb.o)
  "_SecTaskCreateFromSelf", referenced from:
      _darwin_detach_kernel_driver in libusb-1.0.a(darwin_usb.o)

Looks like this can be solved by adding the Security framework to library link requirements in CMakeFiles.txt:

Remaining support for macOS 10.15 will end with release v1.7.1.
Newer versions will not be officially supported.
Thus there will be no attempt to fix this.
