libzmq not (properly?) linking to libpgm (OpenPGM) on openSUSE Tumbleweed

[mbalmer]

Issue description

cmake build on openSUSE Tumbleweed does not correctly link to OpenPBM (libpgm). The following command is being used:

cd build; cmake -DCMAKE_INSTALL_PREFIX=../inst \ -DCMAKE_RULE_MESSAGES=OFF -DZMQ_BUILD_TESTS=OFF \ -DWITH_DOCS=OFF -DWITH_OPENPGM=yes \ ../../../external/lgplv3/zeromq-4.3.4; make && make install

(ZeroMQ source code has been unpackaged in ../../../external/lgplv3/zeromq-4.3.4)

Environment

• libzmq version (commit hash if unreleased):

4.3.4

• OS:

openSUSE Tumnleweed

Minimal test code / Steps to reproduce the issue

Run above command on openSUSE Tumbleweed.

What's the actual result? (include assertion message & call stack if applicable)

What's the expected result?

A usable libzmq.so ;)

ZeroMQ 4.3.2 builds without problems, so this seems to be some sort of regression.

[mbalmer]

ZeroMQ 4.3.3 shows the same error. So the regression was introduced in 4.3.3, apparently.
