Let's take advantage of this change to also remove OPENSSL_INCLUDE_DIR variables patching.
It will make recipe easier and more future-proof.

@ericLemanissier I also don't know what the issue is with the linkage :(

I'm OK with disabling LTO, but I don't know CCI policy about it.

[ericLemanissier]

My ideas are not very clear regarding LTO interaction with conan, but I think that as soon as there is one LTO object file, then the linker must use the LTO flag. This means that conan would have to magically inject the LTO flag when linking a project, if any of the requirements use LTO. This is quite an important bit of circuitry, which I don't think is implemented in conan yet.

The following paragraph is most probably based on a false premise:
when linking a program with LTO (as a consumer), all the object files (conan requirements) need to be compiled with LTO. So it does not seem to me that it can work, except if conan treats LTO option of recipes as a "special" option, and automatically checks that the full dependency graph uses LTO during validate step.

[ericLemanissier]

@SSE4 @uilianries What do you think about this one ?

[SSE4]

IMO LTO and few other flags (e.g. RTTI, exceptions, etc.) fall into the category that should be enabled for all libraries, but we're not modelling them right now. I'd assume LTO=off by default for now.
