Fixed CMake Missing variable is: CMAKE_ASM_COMPILE_OBJECT in PNG build #25631 Error message with `-DBUILD_PNG=ON` on ARM64: ``` -- Configuring done CMake Error: Error required internal CMake variable not set, cmake may not be built correctly. Missing variable is: CMAKE_ASM_COMPILE_OBJECT -- Generating done CMake Generate step failed. Build files cannot be regenerated correctly. ``` ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [x] There is a reference to the original bug report and related work - [ ] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [ ] The feature is well documented and sample code can be built with the project CMake
