This avoids a cryptic DTC failure when compiling trying to compile native_posix with a missing gcc or clang. REQUIRED is available since CMake 3.18 Example with clang, cryptic error without this commit: ``` ZEPHYR_TOOLCHAIN_VARIANT=llvm west build \ -p -b native_posix samples/hello_world/ -- Found toolchain: host (clang/ld) <= this is wrong -- Found Dtc: /usr/bin/dtc (found suitable version "1.6.1", minimum ... -- Found BOARD.dts: zephyr/boards/posix/native_posix/native_posix.dts CMake Error at /zephyr/cmake/modules/dts.cmake:191 (message): command failed with return code: No such file or directory Call Stack (most recent call first): zephyr/cmake/modules/zephyr_default.cmake:113 (include) zephyr/share/zephyr-package/cmake/ZephyrConfig.cmake:66 (include) zephyr/share/zephyr-package/cmake/ZephyrConfig.cmake:92 (include_boil... CMakeLists.txt:5 (find_package) ``` Well hidden behind the scenes, dts.cmake fails above because it invokes `CMAKE_C_COMPILER-NOTFOUND` With this commit: ``` ZEPHYR_TOOLCHAIN_VARIANT=llvm west build \ -p -b native_posix samples/hello_world/ -- Found toolchain: host (clang/ld) <= this is still wrong CMake Error at zephyr/cmake/compiler/clang/generic.cmake:7 (find_program): Could not find CMAKE_C_COMPILER using the following names: clang ``` Signed-off-by: Marc Herbert <marc.herbert@intel.com>
