CMake build of coin broken on macOS apple silicone?

[kjelloh]

I tried to build coin on macOS Sonoma 14.6 Apple silicone as indicated on the README for macOS INSTALL (https://github.com/coin3d/coin/blob/master/INSTALL ). I tried:

cmake -Hcoin -Bcoin_build -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=/Users/name/Coin3D
              -DCOIN_BUILD_DOCUMENTATION=OFF -DCOIN_BUILD_MAC_FRAMEWORK=OFF

But I get cmake error:

CMake Error: File /Users/kjell-olovhogdahl/Documents/GitHub/conan_coin3d/coin/src/Coin.pc.cmake.in does not exist.
CMake Error at coin/src/CMakeLists.txt:395 (configure_file):
  configure_file Problem configuring file

CMake Error: File /Users/kjell-olovhogdahl/Documents/GitHub/conan_coin3d/coin/src/coin.cfg.cmake.in does not exist.
CMake Error at coin/src/CMakeLists.txt:398 (configure_file):
  configure_file Problem configuring file

These files are in the root, not in the src subfolder what I can see.
Am I doing something wrong and or how should I build coin?

PS: I initiated a try to make a conan package for coin (https://github.com/kjelloh/conan_coin3d )

Strange, did you built on a newly created build dir or reused one from a previous attempt while building a framework? In the latter case start from a fresh build dir or delete the CMakeCache.txt file from the build folder. CMake caches the values of its variables from the configure state there. Additionally, can you add a message print before line 395 in coin/src/CMakeLists.txt and output the value of CMAKE_SOURCE_DIR, what is its value? E.g. add the command message(STATUS "value of cmake_source_dir: ${CMAKE_SOURCE_DIR}")?
