Where can I download the following dependency libraries？

set(TOOLCHAIN_DIR /opt/atk-dlrv1126-toolchain)

set(CMAKE_C_COMPILER ${TOOLCHAIN_DIR}/usr/bin/arm-linux-gnueabihf-gcc)
set(SYSROOT ${TOOLCHAIN_DIR}/arm-buildroot-linux-gnueabihf/sysroot/usr/include)
set(CMAKE_SYSROOT ${TOOLCHAIN_DIR}/arm-buildroot-linux-gnueabihf/sysroot)
