MINOR: [C++] Prepend CONDA_PREFIX to CMAKE_PREFIX_PATH when set (#414)
CI started failing due to linker errors that looked like mixed up
OpenSSL,
https://github.com/apache/arrow-cookbook/actions/runs/36902765632. I
think this was caused by the compilers>2 bump we've seen elsewhere.
This updates the C++ CMakeLists to prepend CONDA_PREFIX when found so
conda-installed versions are used. I think an alternative fix would have
been to add cmake to the conda prefix.
