hipcc: CMake 3.21.1 breaks ROCm CMakeLists.txt
This commit ff0d2858 seems to prevent user specified CXX compiler as hipcc and overrides it with clang++ which may not be desirable. It breaks existing CMakeFiles that include checks for "hipcc" as in line 158 above. Is there a way to force CMAKE_CXX_COMPILER to "hipcc" in cmake 3.21? There is no issue in cmake 3.20.
Suggested fix: ff0d2858 (comment 998708)
