-------------------------------------
Summary: CMake's find_package(Parquet) does not find Parquet with
Arrow 3.0.0
Key: ARROW-12175
URL: https://issues.apache.org/jira/browse/ARROW-12175
Project: Apache Arrow
Issue Type: Bug
Components: C++
Affects Versions: 3.0.0
Environment: RHEL 7.6
Spack environment with CMake 3.15.7
Reporter: Matthias Wolf
Hello,
I just updated a small utility that converts binary data to Parquet from Arrow
0.15 to 3.0, and noticed that CMake could not resolve {{find_package(Parquet
REQUIRED)}}, as my installation tree of Arrow contained
{{…/share/cmake/arrow/ParquetConfig.cmake}}, but CMake seems to be expecting
{{…/share/cmake/*parquet*/ParquetConfig.cmake.}}
Creating a symbolic link from the {{arrow}} directory to a {{parquet}}
directory solved CMake's find procedure. Alternatively, I ended up at this
work-around that did not require me modifying my local install tree:
{code:java}
find_package(Arrow REQUIRED)
get_filename_component(MY_SEARCH_DIR ${Arrow_CONFIG} DIRECTORY)
find_package(Parquet REQUIRED HINTS ${MY_SEARCH_DIR})
{code}
Is this expected behavior? I went through the CMake code and found that there
is only one installation directory for all CMake files:
{{ARROW_CMAKE_INSTALL_DIR}} — I would expect this to be specific to the
libraries exported.
Thanks,
Matthias
