cmake: Suppress compiler warnings from capnproto headers #146

   ryanofsky commented at 4:50 pm on February 3, 2025: collaborator

   Tweak target_link_libraries calls to correctly declare dependencies on capnproto libraries as public, so capnproto include directories get correctly added to downstream targets. Without this, compiler warnings can be triggered from capnproto headers because they are not treated like external headers.

   Fixes https://github.com/chaincodelabs/libmultiprocess/issues/138

   This should be an alternative to #141

3. cmake: Simplify capnp include handling

   Stop using lower level target_include_directories to add
   CAPNP_INCLUDE_DIRECTORY includes. This is no longer needed now that newer
   capnproto releases provide targets that set their own includes.
   
   This change is based on some similar cleanups originally implemented by
   Cory Fields <cory-nospam-@coryfields.com> in
   https://github.com/chaincodelabs/libmultiprocess/pull/141
