This will test cmake lang support: CXX and Fortran

I. Prepare

1. You must install cmake version 3.18 or above to support LINK_LANGUAGE. Otherwise, Fortran build will fail. To download the latest cmake, see https://cmake.org/download/.
2. If there is no Fortran on your system, you must install it via, sudo apt install gfortran

II. Build

mkdir -p build; cd build
rm -rf *;
CXX="$(hipconfig -l)"/clang++ FC=$(which gfortran) cmake -DCMAKE_PREFIX_PATH=/opt/rocm ..
cmake ..
make

Note, users may need to add AMD GPU support, if test failed, for example,

CXX="$(hipconfig -l)"/clang++ FC=$(which gfortran) cmake -DCMAKE_PREFIX_PATH=/opt/rocm -DAMDGPU_TARGETS="gfx1102" ..

To enable compiler auto detection of gpu users may need to add ADMGPU support as command line option, if test failed to run, for example,

CXX="$(hipconfig -l)"/clang++ FC=$(which gfortran) cmake -DCMAKE_PREFIX_PATH=/opt/rocm -DAMDGPU_TARGETS=native ..

III. Test

./test_fortran
 Succeeded testing Fortran!

./test_cpp
Device name AMD Radeon Graphics
PASSED!
