Describe the bug
Using a Mac with XCode 15.0, configuring the CMake build and running cmake --build . --config Release (internally, this uses a the Makefile generator) gives this error:

To Reproduce
Steps to reproduce the behavior:

  1. See above, configure CMake and run cmake --build . --config Release

Expected behavior
Release binaries of BinDiff being built.

Screenshots
N/A

Environment (please complete the following information):

  • OS and version: macOS Sonoma, XCode 15.0
  • Locale: US English
  • Disassembler and version: N/A

Additional context
As a workaround, the "classic" linker ld64 can be used instead of the new ld_prime one. See the XCode 15.0 Release Notes.
