Hello,
On Ubuntu, I managed to get a local external (i.e., to Arrow) project to build
against a locally and custom-built Arrow project working using the following:
* Locally build Arrow and install it to a directory $ARROW_ROOT_DIR
* Configure the external project build using: cmake
-DARROW_CMAKE_DIR=$ARROW_ROOT_DIR/lib/cmake/arrow
* Include the following cmake-directives in the external project (which
uses Arrow, ArrowDataset, and Parquet):
set(CMAKE_MODULE_PATH ${ARROW_CMAKE_DIR})
set(Arrow_DIR ${ARROW_CMAKE_DIR})
set(ArrowDataset_DIR ${ARROW_CMAKE_DIR})
set(Parquet_DIR ${ARROW_CMAKE_DIR})
* Build the external project and run the executable with
LD_LIBRARY_PATH=$ARROW_ROOT_DIR/lib
For some reason, I had to set a "*_DIR" cmake-variable for each Arrow
dependency, which is not as clean as one would like. Without these, cmake fails
to find the local Arrow project install and mixes it up with a system-wide
Arrow installation, leading to the external project failing to build. If you
know of a cleaner way to configure the external project, please advise.
Thanks,
Yaron.

Subject: [C++] Build/Link against master / custom branch
Hello!
We are trying to write some program similar to:
https://github.com/apache/arrow/blob/master/cpp/examples/arrow/execution_plan_documentation_examples.cc
to test Arrow compute engine performance.
We would like to build the example against Arrow default because we added a
"square root" function to it. I wonder if there is an easy way to build/link my
program against github master / custom branch or if we should put it under
cpp/examples/arrow and compile arrow lib and the main program together?
Thanks,
Li
