If I manually build libpng I don't get this error: git clone https://github.com/glennrp/libpng
cd libpng
cmake .

cp -r libpng16.a /mnt/disk/vcpkg/installed/arm64-linux/lib/libpng16.a

I'll take a look this issue. @PhoebeHui you can assign arm64-linux/arm-linux build issues to me if your team doesn't have time to work on it. |

…o _csc_OPTIONS to fix issue microsoft#13395. Root cause: In script mode, cmake won't populate CMAKE_SYSTEM_PROCESSOR parameter automatically. That parameter is required by libpng to configure build parameters. To fix this issue, we need explicitly pass that parameter via _csc_OPTIONS. Verify: On arm64-linux and arm-linux host, run `./vcpkg install tesseract:arm64-linux` and `./vcpkg install tesseract:arm-linux`.

Host Environment
To Reproduce
Steps to reproduce the behavior:
./vcpkg install tesseractFailure logs
Tail of
vcpkg/buildtrees/tesseract/install-arm64-linux-dbg-out.log:Additional context
It looks like libpng failed to detect that NEON instructions are available and compiled without those
*_neonfunctions?Or is it possible that it's linking to the system libraries (I haveVCPKG_FORCE_SYSTEM_BINARIES=on) and they are not compiled with those functions?If a maintainer wants to test the issue, I can provide credentials to an arm64 AWS machine with that behavior (email me [email protected])
