Unable to build tor statically (no linkable openssl found)

I try to build tor statically. While configure tor it errors with:

checking for openssl directory... configure: WARNING: Could not find a linkable openssl.  If you have it installed somewhere unusual, you can specify an explicit path using --with-openssl-dir
configure: WARNING: On Debian, you can install openssl using "apt-get install libssl-dev"
configure: error: Missing libraries; unable to proceed.

I tried:

• with several tor versions
• with several openssl versions, using several paths to openssl.
• with ubuntu, debian, in container, locally (ubuntu 20.04) etc. I got always the same error.
• several different options for openssl, libevent
• with openssl-dev and path point to it

I don't know if it's a but however i spent now 1-2 days on this. The error should be more precise anyway.

Here a complete example:

FROM debian

RUN mkdir /tor

RUN apt update && apt upgrade -y

RUN apt install -y exa
RUN apt install -y git

RUN apt install -y build-essential automake pkgconf
RUN apt install -y zlib1g-dev libsystemd-dev
RUN apt install -y libtool autopoint
