thanks for the feedback. fixed it just now. the new script works.

main changes are:

1. Install cmake "apt-get -y install build-essential autoconf libtool git-core cmake"

2. Updated the build/install for libheif, thanks.

cd /usr/src/libheif/

mkdir build

cd build

cmake --preset=release ..

make -j$(nproc)

make install

3. Updated to php8.2-dev rather than 8.1

Thanks again.
