[Qemu-devel] [RFC PATCH v2 5/6] curl: build as shared library

[Fam Zheng <famz@redhat.com>]

Curl block driver is built as shared object module when enabled.
We have per object cflags and libs support now, move CURL_CFLAGS and
CURL_LIBS from global option variables to a per object basis.

"make install" is not installing it yet, manually copy it to
${prefix}/qemu/block/curl.so to make it loaded.
