[farhangnaderi]

Describe the bug

Multiples build errors on macOS 15.5

To Reproduce

1. pull main branch
2. follow this [Docs] macOS Dev environment installation #25204
3. run make px4_sitl gz_x500
4. The errors below should pop up:

• I disabled OpticalFlow for this:

CMake Error at CMakeLists.txt:34 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

• Additionally, I changed

  PX4-Autopilot/cmake/px4_add_common_flags.cmake

  Line 76 in 84cdc05

  -Wdouble-promotion

  to -Wno-double-promotion
• Also

  PX4-Autopilot/src/modules/simulation/gz_plugins/moving_platform_controller/MovingPlatformController.cpp

  Line 243 in 84cdc05

  _force += feedback_force * gz::math::Vector3d(scaling, scaling, 1.);

  to
  _force += feedback_force * gz::math::Vector3d(static_cast<double>(scaling), static_cast<double>(scaling), 1.0);
