libmpp ? rk3588\external\mpp ，Official mpp code is compiled without libmpp，only libmpp_rc.a libmpp_codec.a libmpp_base.a ...

rk@linaro-alip:~/xxw$ sudo find / -name libmpp*

我是这样解决的，倒是编译通过了

ln -s /usr/local/lib/librockchip_mpp.so /usr/local/lib/libmpp.so
ln -s /usr/local/lib/librockchip_vpu.so /usr/local/lib/libvpu.so

记得在/etc/profile中添加环境变量:

export CPLUS_INCLUDE_PATH=/usr/local/include/rockchip/:$CPLUS_INCLUDE_PATH
export PATH=/usr/local/lib/:$PATH

On my board it is called librockchip_mpp.so on /usr/lib/aarch64-linux-gnu/librockchip_mpp.so
I modify CMakeLists.txt like this:

target_link_libraries(mpp_linux_demo rockchip_mpp pthread drm)
