Bug#928702: libxmlrpc-core-c3-dev: 'xmlrpc-c-config client --libs' spits out -lcurl but the package does not depend on 'libcurl-dev'

[Arkadiusz Hiler <arek@hiler.eu>]

Package: libxmlrpc-core-c3-dev
Version: 1.33.14-4
Severity: normal

Dear Maintainer,


Building a project that requires xmlrpc but does not explicitly require libcurl fails.

The project: https://gitlab.freedesktop.org/drm/igt-gpu-tools

The result:
  $ ninja -C build
  /usr/bin/ld: cannot find -lcurl
  collect2: error: ld returned 1 exit status
  [14/711] Compiling C object 'tests/59830eb@@kms_atomic@exe/kms_atomic.c.o'.
  ninja: build stopped: subcommand failed.

And this is because:
  $ xmlrpc-c-config client --libs
  -L/usr/lib/x86_64-linux-gnu   -lxmlrpc_client -lxmlrpc  -lxmlrpc_xmlparse -lxmlrpc_xmltok -lxmlrpc_util -lcurl

  $ apt depends libxmlrpc-core-c3-dev

  $ apt depends libxmlrpc-core-c3
  libxmlrpc-core-c3
  Depends: libc6 (>= 2.14)
  Depends: libcurl3 (>= 7.16.2)
