ARROW-26: Add instructions for enabling Arrow C++ Parquet adapter build

This patch documents the workflow for building the optional Arrow-Parquet C++ integration.
I originally thought about adding an option to build it in Arrow's thirdparty, but it immediately
results in a dependency-hell situation (Parquet requires Thrift, Boost, snappy, lz4, zlib)

+## Building Arrow-Parquet integration
+
+To build the Arrow C++'s Parquet adapter library, you must first build [parquet-cpp][1]:
+
+```bash
+# Set this to your preferred install location
+export PARQUET_HOME=$HOME/local
+
+git clone https://github.com/apache/parquet-cpp.git
+cd parquet-cpp
+source setup_build_env.sh
+cmake -DCMAKE_INSTALL_PREFIX=$PARQUET_HOME
+make -j4
+make install
+```
+
+Make sure that `$PARQUET_HOME` is set to the installation location. Now, build
+Arrow with the Parquet adapter enabled:
+
+```bash
+cmake -DARROW_PARQUET=ON
+```
