> Can we just disable the whole pkg-config search completely? Our builds
have CMake metadata, and `find_package(${PACKAGE_NAME} REQUIRED)` should work
in the vast majority of cases (even moreso with `CONFIG` mode), and especially
for gprc.
We can add an option to disable pkg-config support. But if we disable
pkg-config support, conda users can't find Apache Arrow C++ by pkg-config. I'm
not familiar with conda but I think that there are users who use pkg-config to
find external packages.
