> [C++] CMake's find_package(Parquet) does not find Parquet with Arrow 3.0.0

> 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
