In the file INSTALL.md requirements for OpenSSL - 3.0, in Cmakelists.txt - 3.4

I have an Ubuntu 24.04.4 LTS system deployed in WSL.

In the file INSTALL.md requirements for OpenSSL - 3.0, in Cmakelists.txt - 3.4
What should I believe?

I changed in CMakeLists.txt versions before 3.0 give an error when building.
I posted a piece of debugging output:

Hi, @strvv! If your goal is simply to build the gost-engine engine/provider rather than investigate issues with INSTALL.md, I'd recommend using OpenSSL 3.6 or newer.

If you're using OpenSSL 3.0, it's better to disable the provider build (this version does not fully support providers) and build only the engine.

See to find out, how gost-engine is built on Ci:
https://github.com/gost-engine/engine/blob/master/.github/script.sh#L10

Try:

cmake --build . --config Release -DGOST_BUILD_ENGINE=1 -DGOST_BUILD_PROVIDER=0
