When apt was upgraded, the '-DCMAKE_DISABLE_FIND_PACKAGE_Zstd=True' was dropped. However, it was there to fix do_compile error when ccache is enabled. See details in the following commit. """ commit 0aa7d612b8b7e5f14b4ed38f2a32b3f7eefca31c Author: Robert Yang <liezhi.yang@windriver.com> Date: Tue Jan 19 01:23:45 2021 -0800 apt: Fix do_compile error when enable ccache Fixed: apt-pkg/libapt-pkg.so.5.0.2: undefined reference to `ZSTD_endStream' collect2: error: ld returned 1 exit status This is because ccache-native depends on zstd-native which makes apt wronly find it. Disable zstd for apt to fix the problem. """ Now we are meeting do_compile failure again when enabling ccache, so add it back to solve the problem.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
