+Subject: [PATCH] Export binaries only for native build
+
+By default, the cmake configuratione exports all generated files,
+so when using the generated cmake file with a find_package command,
+it verifies that these files actually exist.
+
+When using the cross-compiled version of capnproto, the generated
+binaries are not available in RECIPE_SYSROOT (since they can be
+used as RDEPENDS only, but not usable as DEPENDS), and due to
+this the compilation fails.
+
+To avoid this, check during the compilation of capnproto if it is
+being cross-compiled, or not. If is it cross-compiled, then only
+install the generated binary files in their final location, but
+don't export them. When not cross-compiling, do the same, but also
+export the files (which is the default behavior).
+
+Upstream-Status: Inappropriate [oe specific: see above message]
