AutotoolsToolchain compiler_executable mapping for RC win compiler

[memsharded]

Ok, I just realized. The openssl recipe uses the AutotoolsToolchain that defines the compiler mapping as: compilers_mapping = {"c": "CC", "cpp": "CXX", "cuda": "NVCC", "fortran": "FC"}

In other words, it is not prepared for cross-compiling from Linux -> Windows and defining the RC compiler.

So the issue needs to be addressed in both places, opening another ticket in the Conan client
