[Build] Inconsistent naming of lib directories

Describe the issue

The official release for linux (onnxruntime-linux-x64-xxx.tgz) contains folder 'lib' with .so files. Yet, file lib/cmake/onnxruntime/onnxruntimeTargets-release.cmake refers to this location as 'lib64' in command:

set_target_properties(onnxruntime::onnxruntime PROPERTIES
  IMPORTED_LOCATION_RELEASE "${_IMPORT_PREFIX}/lib64/libonnxruntime.so.1.20.1"
  IMPORTED_SONAME_RELEASE "libonnxruntime.so.1"
  )

This produces CMake error when CMakeLists.txt contains find_package(onnxruntime CONFIG)

Urgency

No response

Target platform

Linux x64

Build script

Basic CMakeLists.txt to reproduce this fault may look like this:

cmake_minimum_required(VERSION 3.15)

project(test)

find_package(onnxruntime CONFIG)

and is executed:

$ cmake </path/to/CMakeLists.txt> -DCMAKE_PREFIX_PATH=</path/to/onnxruntime/release>

Error / output

CMake Error at /home/ubuntu/libs/onnxruntime-linux-x64-1.20.1/lib/cmake/onnxruntime/onnxruntimeTargets.cmake:84 (message):
The imported target "onnxruntime::onnxruntime" references the file

 "/home/ubuntu/libs/onnxruntime-linux-x64-1.20.1/lib64/libonnxruntime.so.1.20.1"

but this file does not exist. Possible reasons include:

• The file was deleted, renamed, or moved to another location.

• An install or uninstall procedure did not complete successfully.

• The installation package was faulty and contained

  "/home/ubuntu/libs/onnxruntime-linux-x64-1.20.1/lib/cmake/onnxruntime/onnxruntimeTargets.cmake"

but not all the files it references.

Start with lib/cmake/onnxruntime/onnxruntimeTargets-release.cmake and compare its referenced lib64 path with the lib directory in the official Linux release archive. Reproduce the issue using the provided CMakeLists.txt and CMAKE_PREFIX_PATH. Done means find_package(onnxruntime CONFIG) succeeds without referencing a nonexistent library path.
