I'm trying to cross-compile OpenCV into Raspberry Pi 3, but I got stuck at linking libzlib.a

My CMAKE command is as follows:

cmake  -D CMAKE_BUILD_TYPE=RELEASE -DENABLE_NEON=ON -DBUILD_LIB=ON -DBUILD_ZLIB=ON \
-DCMAKE_AR=${AR} \
-DCMAKE_TOOLCHAIN_FILE=/home/ytan/Dev/opencv/platforms/linux/armv8-rpi3-linux-gnueabihf.toolchain.cmake -D CMAKE_INSTALL_PREFIX=~/Dev/build-pi3/opencv ..

And when I run make, I get this error:

[  1%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/inftrees.c.o

I was referring to this post, but no one seemed to have answered it. I'm using Xubuntu 16.04, and used crosstool-ng to build my toolchain (ct-ng armv8-rpi3-linux-gnueabihf)

Help, anyone?

I was referring to this This post, is 3 years old, but no one seemed to have answered it. Even Jesus (OP) gave up.
