----------------------------------------

             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'
cd /tmp/tmp.uDaq1bz2ia/cmake-build-debug-diascld-36/_deps/arrow-download-build/lz4_ep-prefix/src/lz4_ep && /scratch/chrysoge/pelago-llvm-14/opt/bin/cmake -P /tmp/tmp.uDaq1bz2ia/cmake-build-debug-diascld-36/_deps/arrow-download-build/lz4_ep-prefix/src/lz4_ep-stamp/lz4_ep-build-DEBUG.cmake

  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.
