CMake Deprecation Warning at CMakeLists.txt:4 (cmake_policy): The OLD behavior for policy CMP0026 will be removed from a future version of CMake. The cmake-policies(7) manual explains that the OLD behaviors of all policies are deprecated and that a policy should be set to OLD only under specific short-term circumstances. Projects should be ported to the NEW behavior and not rely on setting a policy to OLD. -- VC4CL standard library headers found: /home/dietpi/opencl/VC4C/../VC4CLStdLib/include/ -- The C compiler identification is GNU 12.2.0 -- The CXX compiler identification is GNU 12.2.0 -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working C compiler: /usr/bin/cc - skipped -- Detecting C compile features -- Detecting C compile features - done -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Check for working CXX compiler: /usr/bin/c++ - skipped -- Detecting CXX compile features -- Detecting CXX compile features - done -- Using CMake 3.14+ FetchContent to include dependencies... -- CLang compiler found: /usr/bin/clang -- LLVM-dis found: /usr/bin/llvm-dis-14 -- LLVM-as found: /usr/bin/llvm-as-14 -- LLVM-link found: /usr/bin/llvm-link-14 -- Performing Test HAVE_FFI_CALL -- Performing Test HAVE_FFI_CALL - Success -- Found FFI: /usr/lib/arm-linux-gnueabihf/libffi.so -- Performing Test Terminfo_LINKABLE -- Performing Test Terminfo_LINKABLE - Success -- Found Terminfo: /usr/lib/arm-linux-gnueabihf/libtinfo.so -- Found ZLIB: /usr/lib/arm-linux-gnueabihf/libz.so (found version "1.2.13") -- Found LibXml2: /usr/lib/arm-linux-gnueabihf/libxml2.so (found version "2.9.14") -- Compiling LLVM library front-end with LLVM in version 14.0.6 located in '/usr/lib/llvm-14/lib' -- Performing Test CMAKE_HAVE_LIBC_PTHREAD -- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Success -- Found Threads: TRUE -- found clang-format: /usr/bin/clang-format -- Configuring done -- Generating done -- Build files have been written to: /home/dietpi/opencl/VC4C/build
