FindParquet.cmake)
> [C++] example parquet-arrow project includes broken FindParquet.cmake
> ---------------------------------------------------------------------
>
> Key: ARROW-8032
> URL: https://issues.apache.org/jira/browse/ARROW-8032
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Affects Versions: 0.17.0
> Environment: NA
> Reporter: Tomasz Cheda
> Priority: Minor
> Labels: beginner, easyfix
> Original Estimate: 0.25h
> Remaining Estimate: 0.25h
>
> The example project at
> [https://github.com/apache/arrow/tree/master/cpp/examples/parquet/parquet-arrow/cmake_modules]
> includes a broken version of FindParquet.cmake (
> [https://github.com/apache/arrow/blob/master/cpp/examples/parquet/parquet-arrow/cmake_modules/FindParquet.cmake]
> )
> The other module is, correctly, a link to FindArrow.cmake in
> [https://github.com/apache/arrow/tree/master/cpp/cmake_modules]
> For the curious, the broken part is assuming that FindPkgConfig variables
> will be set if the module is found - this can be false if the include
> directory is /usr/include. This can be controlled by one of FindPkgConfig's
> config variables, but the default behaviour changes as of CMake 3.10. It then
> erroneously reports that Parquet has not been found.
> This is not a major bug, but I based my build files off of those in the
> example directory and it took me a LONG time to figure out the error. It can
> be really confusing for new users and is simple to fix.
