In other words, don't add the .hpp11 files to the BUILD.gn
That's because GN doesn't recognize .hpp11 extension as a C/C++
header file.
See https://bugs.chromium.org/p/gn/issues/detail?id=311
Instead, client dependencies should #include the .hpp11 file directly
even though that seems to hide it away from GN's visibility.
That seems wrong, but it does work.
