Building on the ARM64 Architecture

[LiaV211]

Hello everyone,

I am currently attempting to build locally on the Arm64 architecture using the steps outlined in the following link:
https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts/blob/master/docs/user/BuildLocally.md
However, I have encountered some challenges with the "ortools" during the build process. Despite cloning and manually building, I am encountering the following issue:

Could not find a package configuration file provided by "ortools" with any
of the following names:
ortoolsConfig.cmake
ortools-config.cmake
Add the installation prefix of "ortools" to CMAKE_PREFIX_PATH or set
"ortools_DIR" to a directory containing one of the above files. If
"ortools" provides a separate development package or SDK, be sure it has
been installed.

I have tried setting the path and attempted the same process again with or-tools, Abseil, Protobuf, ZLIB, and others, only to face similar issues.

CMake Error at /home/ubuntu/OpenROAD-flow-scripts/dependencies/share/cmake-3.21/Modules/CMakeFindDependencyMacro.cmake:47 (find_package):
Could not find a package configuration file provided by "absl" with any of
the following names:
abslConfig.cmake
absl-config.cmake
Add the installation prefix of "absl" to CMAKE_PREFIX_PATH or set
"absl_DIR" to a directory containing one of the above files. If "absl"
provides a separate development package or SDK, be sure it has been
installed.

If anyone has encountered and overcome a similar problem or has suggestions to offer, I would greatly appreciate your assistance. Thank you for your time and support.
