+# rice-c/build.rs builds the internal rice-proto C library in-tree (via

+# The generated rice-proto.pc carries an absolute prefix pointing at the
+# in-build OUT_DIR (.../rice-c-<hash>/out/rice-proto-cbuild). pkgconf prepends
+# PKG_CONFIG_SYSROOT_DIR (=recipe-sysroot) to that already-absolute prefix,
+# producing a doubled, non-existent include path and making build.rs panic
+# with "Could not find rice-proto.h header". The internal lib is not staged in
+# the sysroot, so no sysroot rewriting must be applied to its .pc file.
+# Clear PKG_CONFIG_SYSROOT_DIR for the build so the internal prefix is used
+# verbatim. openssl-sys is the only other pkg-config consumer here, so feed it
+# the sysroot openssl explicitly (this bypasses its pkg-config probe entirely,
+# see openssl-sys find_normal.rs) to keep it pointed at the target sysroot.
