Bug fix for Samples

Summary

In the DirectProgramming/C++/StructuredGrids/iso3dfd_omp_offload/src/CMakeLists.txt, the default cmake instructions shown in the official guidance cmake -DVERIFY_RESULTS=0 .. cannot really successfully make-build the project successfully and report the below messages, indicating that the compiler is not set properly.

In the CMakeLists file, the 3rd line should be changed from set(CMAKE_CXX_COMPILER "icpx") to set(CMAKE_CXX_COMPILER icpx). Or we should explicitly declare the compiler options.

Mở DirectProgramming/C++/StructuredGrids/iso3dfd_omp_offload/src/CMakeLists.txt và kiểm tra thiết lập trình biên dịch ở dòng 3. Trước tiên, hãy tái hiện cấu hình cmake -DVERIFY_RESULTS=0 .. được ghi trong tài liệu và lệnh make -j. Được xem là hoàn tất khi sample được cấu hình và build mà không gặp các lỗi tùy chọn trình biên dịch đã báo cáo.
