----------------------------------------
Summary: [C++] LZ4 fails to build when depending on arrow via CMake
Key: ARROW-16572
URL: https://issues.apache.org/jira/browse/ARROW-16572
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Hamish Nicholson
When depending on arrow as an external CMake project in another CMake project,
and attempting to build LZ4 from source the following occurs:
{code:java}
[ 11%] Performing build step for 'lz4_ep'

(message):
Stopping after outputting logs. {code}
(/tmp/tmp.uDaq1bz2ia is the root CMake source directory of the parent CMake
project)
This is due to the use of `CMAKE_SOURCE_DIR` instead of
`CMAKE_CURRENT_SOURCE_DIR`. I will have a PR up for this shortly.
