I have been trying the "[PATCH v2 1/5] libxenguest: support zstd
compressed kernel" patch, and (assuming I haven't broken anything trying
to migrate it to 4.14) it fails with
onfigure: error: Package requirements (libzstd) were not met:
Package 'libzstd', required by 'virtual:world', not found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables libzstd_CFLAGS
and libzstd_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
configure: error: ./configure failed for tools
I didn't give it any zstd packages so I would expect this test to fail,
but I would have expected the build to continue and attempt to use the
zstd code in the xen tree instead.
