Subject: rsocket: Build librspreload library as part of build
X-Git-Tag: v1.0.16~5
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=934949885dc5db0c30a70378b7fc8c36d512e32f;p=~shefty%2Flibrdmacm.git

rsocket: Build librspreload library as part of build

Build the rsocket preload library as part of the build.  To reduce the
risk of the preload library intercepting calls without the user's
knowledge, the preload library is installed into {_libdir}/rsocket.
