Steps to reproduce the issue

I am trying to install the open3d from source. Ran into issues with python version during build.

Error message

-- CMAKE_BUILD_TYPE is set to Release.
-- Downloading third-party dependencies to /home/user/Gopi/Open3D/3rdparty_downloads
CMake Deprecation Warning at CMakeLists.txt:189 (cmake_policy):
  The OLD behavior for policy CMP0072 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

  PATH.

@Gopi-GK02 @srivatsanadi Notice that cmake complains about not finding Development Development.Module Development.Embed, i.e. it finds Interpreter module, but not other modules. See https://github.com/isl-org/Open3D/blob/main/CMakeLists.txt#L328

You are probably missing python development packages.

If you follow docs, then python3-dev should have been installed via install_deps_ubuntu.sh
