Existing Sample Changes

Description

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.

Or we should explicitly declare the compiler options.
