  #   CMake Error at cmake_builder/linphone_package/cmake_install.cmake:49 (file):

  #     file INSTALL cannot find

  #     "/build/linphone-desktop-.../build/linphone-sdk/desktop//nix/store/.../bin":

  #     No such file or directory.

  #

  # If someone is able to figure out how to fix that, great. For now, just

  # trying to pick all the relevant files to the output.

  #

  # Also, the exec path in linphone.desktop file remains invalid, pointing to

  # the build directory, after the whole nix build process. So, let's use sed to

  # manually fix that path.

  # It is quite likely that there are some other files still missing and

  # Linphone will randomly crash when it tries to access those files. Then,

  # those just need to be copied manually below.
