helper file. We can't just always include this file (even if we

|
know we have <infiniband/verbs.h>) because there are some inline
|
|
functions in that file that invoke ibv_* functions. Some linkers
|
|
(e.g., Solaris Studio Compilers) will instantiate those static
|
|
inline functions even if we don't use them, and therefore we need
|
|
to be able to resolve the ibv_* symbols at link time.
|
|
|
|
Since -libverbs is only specified in places where we use other
|
|
ibv_* functions (e.g., the OpenFabrics-based BTLs), that means that
|
|
linking random executables can/will fail (e.g., orterun).
