 ### Build Examples
 
 After installing the core libraries, you can build the examples:
 
 ```bash
 cd iceberg-cpp/example
 mkdir build && cd build
-cmake .. -DCMAKE_PREFIX_PATH=/tmp/iceberg
+cmake .. -DCMAKE_PREFIX_PATH=/path/to/install
 cmake --build .
 ```
 
+If you are using provided Apache Arrow, you need to include `/path/to/arrow` in `CMAKE_PREFIX_PATH` as below.

+```bash
+cmake .. -DCMAKE_PREFIX_PATH="/path/to/install;/path/to/arrow"
