Worked on the alibaba/MNN repository to address installation reliability and cross-platform consistency, focusing on the build system configuration using CMake. Delivered a targeted fix for Windows by updating the CMake install rule to use RUNTIME DESTINATION bin, ensuring that DLLs are correctly placed in the bin directory during installation. This adjustment resolved DLL placement issues that previously led to installation failures for Windows users and brought packaging behavior in line with Unix-like platforms. The work leveraged expertise in cross-platform development and build system configuration, directly improving the installation experience for downstream applications that depend on the MNN library.
