Update GZ Plugin OpticalFlow CMake configuration for library paths

[farhangnaderi]

Solved Problem

Using .so library format is not what macOS is building (dylib). This approach is more general.

Solution

Changelog Entry

For release notes:

Generalized OpticalFlow GZ plugin library

Alternatives

Not that I know of.

Test coverage

CI is happy + locally tested on macOS and Ubuntu.

CMake Warning (dev) at CMakeLists.txt:176 (find_package):
  Policy CMP0148 is not set: The FindPythonInterp and FindPythonLibs modules
  are removed.  Run "cmake --help-policy CMP0148" for policy details.  Use
  the cmake_policy command to set the policy and suppress this warning.

This warning is for project developers.  Use -Wno-dev to suppress it.

Pull request overview

This PR improves cross-platform compatibility for the OpticalFlow Gazebo plugin by replacing hardcoded .so library extensions with the CMake variable CMAKE_SHARED_LIBRARY_SUFFIX. This allows the build system to work correctly on macOS (which uses .dylib) in addition to Linux (which uses .so).

• Updated BUILD_BYPRODUCTS specification to use platform-independent library suffix
• Updated OpticalFlow_LIBS cache variable to use platform-independent library suffix
