  1. I am trying to work with the following library: https://github.com/apache/parquet-cpp. Once built, the library has a number of shared objects generated(libparquet.so,libarrow.so,libsnappy.so,etc). In such a situation to work with this library in my own single source file, I would have to use multiple -I/-L statements in a Makefile probably pointing to specific locations. Is there a shorter, simpler and more efficient way?

  2. Currently when running the example provided: reader-writer.cc, I'm copying the file outside this project in a new folder renaming it to test.cpp. Then I copy the libarrow/libparquet.so files in this directory and run the command as explained here. The compiler runs successfully, but the linker fails with the following log.
