How to compile PCL to android?

Just a guide, and a confirmation of:
using wsl2 on windows 11 can compile PCL to android, with the help of vcpkg.

export ANDROID_NDK_HOME=~/android-sdk/android-ndk-r25c

cd ~
[ ! -d "vcpkg" ] && git clone https://github.com/microsoft/vcpkg.git

cd ~/vcpkg
git checkout 2026.03.18
./bootstrap-vcpkg.sh

cd ~/vcpkg

# Remove the PCL build cache specifically
rm -rf buildtrees/pcl
rm -rf packages/pcl_arm64-android

# Optional: If you think the dependencies (Boost/Eigen) are also messed up:
rm -rf buildtrees/boost
rm -rf buildtrees/flann

# --recurse: Ensures that if a dependency (like Flann) needs an update due to the new vcpkg version, it gets updated too.
./vcpkg install pcl:arm64-android --recurse


rm -rf /root/vcpkg/buildtrees/pcl
VCPKG_MAX_CONCURRENCY=2 ./vcpkg install pcl:arm64-android --recurse --clean-after-build






fsutil.exe file setCaseSensitiveInfo "D:\usp\uhpsj\proj\pcl_android_wsp" enable

sudo cp -r /root/vcpkg/installed/arm64-android/* /mnt/d/usp/uhpsj/proj/pcl_android_wsp/


cd /root/vcpkg/installed/
sudo zip -r /mnt/d/usp/uhpsj/proj/pcl_android_sdk.zip arm64-android/


cd /root/vcpkg
sudo zip -r /mnt/d/usp/uhpsj/proj/vcpkg_scripts.zip scripts/

The PCL version I got is:
