Hi all,
I am trying to write a Julia parquet writer by leveraging the C++ arrow
library. I can build arrow and arrow/parquet and can write out a parquet
file successfully. The next part I need to do is to use the [CxxWrap.jl](
https://github.com/JuliaInterop/CxxWrap.jl) Julia package to call the C++
functions I wrote. However, CxxWrap.jl underlying JlCxx library only has
build examples in CMake, so I am having issues modifying the CMakeLists.txt
to add the arrow and arrow/parquet dependencies.
This is the error I get when I try to run their CMake process, so I should
be able to add something to the CMakeLists.txt file to tell i where to the
find the parquet and arrow libraries right? I am so new to C++ that I am at
lost on how to do this. I have include the CMakeLIst.txt file at the very
end! Thanks for any help and for helping me make a Julia parquet write a
reality.
