Compile under Alpine linux

[ratermir]

First question: Is timescaledb-toolkit available for Alpine linux for PG15?
I didn't find such so I tried to compile it on myself, but so far with no success.

Here is the script I used on "pure" alpine linux.

apk add curl geos-dev proj-dev gdal-dev make gcc musl-dev json-c-dev cargo git
apk add postgresql postgresql-dev

adduser psql -D
su psql
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source "$HOME/.cargo/env"

cargo install --version '=0.7.4' --force cargo-pgx
cargo install cargo-zigbuild

cargo pgx init --pg15 pg_config

git clone https://github.com/timescale/timescaledb-toolkit
cd timescaledb-toolkit/extension

cargo pgx install --release
cargo run --manifest-path ../tools/post-install/Cargo.toml -- pg_config

Everything worked until the command
cargo pgx install --release
which returned
error: cannot produce cdylib for `timescaledb_toolkit v1.16.0-dev (/home/psql/timescaledb-toolkit/extension)` as the target `x86_64-unknown-linux-musl` does not support these crate types

Here is the whole console record:

psql@96b786c4d70e:~/timescaledb-toolkit/extension$ cargo pgx install --release
Using PgConfig("pg15") and `pg_config` from /usr/bin/pg_config

I stepped by the TSDB toolkit documentation 'https://github.com/timescale/timescaledb-toolkit', but I had to change all "pgx" occurances in Cargo.toml to 0.7.4 since with 0.7.1 was not possible to install cargo.

I am completlely new in RUST and PG/TSDB/toolkit building, so if you have any advices, please explain in a little bigger detail.
