Users can now generate the necessary linker args for their own applications using something like: PKG_CONFIG_PATH=build/lib/pkgconfig pkg-config --libs spdk_nvme Dependencies between libraries are included in the generated .pc files, so the user only needs to pass the top-level subsystems or individual SPDK libraries they are using in their application. Modules will automatically be added to the output if the associated library is specified. For example, specifying "spdk_bdev" will include the libraries not only for spdk_bdev, but also all of the bdev modules. Users still need to supply the -Wl,--no-as-needed or -Wl,--whole-archive flags. They cannot be added to the .pc files without increasing the length of the argument string by a factor of 15x to 20x. Modify the test/external_code/hello_world Makefile to use pkg-config to ensure this gets tested at some level in our autotest environment.
