[master]: Opencv not building with cmake version 4.x used in whinlatter release

[LMS-TimoSchuster]

With the new whinlatter release yocto moved the cmake version to 4.x which causes following errors:

|   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.

Adding -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to the recipe is not enough, see:

opencv/opencv#27122

The solution is basically to bump up every cmake_minimum_required < 3.5 to 3.5 via patch file similar to:

opencv/opencv@cb80308#diff-e4ddc642d45c62a456c800502887e68e6c64595da87894090b9f3a0a08817799

Are there plans to move to a newer opencv imx version for whinlatter? If not, I could provide a patch that fixes the build issue for the 4.6.0.imx version.
