It looks like you're down to two real errors:

  CMake Error: File /builds/science-team/arrayfire/debian/output/source_dir/extern/forge/CMakeModules/version.h.in does not exist.
  CMake Error at CMakeModules/AFconfigure_forge_submodule.cmake:47 (configure_file):
    configure_file Problem configuring file

Please try commenting out the configure_file call at the end of
CMakeModules/AFconfigure_forge_submodule.cmake.

  CMake Error at /usr/share/cmake-3.18/Modules/ExternalProject.cmake:2350 (message):
    error: could not find git for clone of clFFT-ext
  Call Stack (most recent call first):
    /usr/share/cmake-3.18/Modules/ExternalProject.cmake:3206 (_ep_add_download_command)
    CMakeModules/build_clFFT.cmake:33 (ExternalProject_Add)
    src/backend/opencl/CMakeLists.txt:15 (include)

Please try adding a build dependency on libclfft-dev and replacing
src/backend/opencl/CMakeLists.txt's inclusion of build_clFFT with a call
to

  find_package(clFFT)

No problem.
