Jiri Daněk created PROTON-2788:
----------------------------------
Summary: proton-c cannot build with openssl outside of system
include directories?
Key: PROTON-2788
URL: https://issues.apache.org/jira/browse/PROTON-2788
Project: Qpid Proton
Issue Type: Bug
Components: proton-c
Affects Versions: proton-c-0.39.0
Reporter: Jiri Daněk
Assignee: Jiri Daněk
I have a cross compile setup. Cmake is able to find openssl, but it is later
not able to include it. This seems like some omission in cmake configs which is
revealed in such unusual environment.
I intend to investigate if there's something to be done, and if it can be fixed
without too much weirdness, I want to fix it. Meanwhile, I'm going to add
-isystem switches to compiler.
