Description
I have jemalloc installed system-wide without the je_ prefix. When I try to compile indexer it fails as follows:
gcc -I . -fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=$WORK=/tmp/go-build -gno-record-gcc-switches -o $WORK/github.com/couchbase/nitro/mm/_obj/_cgo_.o $WORK/github.com/couchbase/nitro/mm/_obj/_cgo_main.o $WORK/github.com/couchbase/nitro/mm/_obj/_cgo_export.o $WORK/github.com/couchbase/nitro/mm/_obj/build.cgo2.o $WORK/github.com/couchbase/nitro/mm/_obj/malloc.cgo2.o $WORK/github.com/couchbase/nitro/mm/_obj/malloc.o -L /home/shaleny/dev/membase/repo-master/build/forestdb -L /home/shaleny/dev/membase/repo-master/build/sigar/src -L /home/shaleny/dev/membase/repo-master/build/platform -L /usr/lib -L /home/shaleny/dev/membase/repo-master/install/lib -ljemalloc

As seen, simply -ljemalloc is passed to gcc, which means that it will use the library found in standard global library paths over the one installed in $PREFIX/install/lib. We should path the full path to jemalloc here and also set the rpath instead.
Note, I do see this in go-install.cmake:
# QQQ TOTAL HACK to enable CGO binaries to find Couchbase-built shared
|
# libraries. This will clearly only work on Linux ELF-based systems,
|
# and only for those libraries which are installed in the correct path
|
# relative to the installed location of the Go executable. I'm still
|
# trying to figure out how to handle this correctly.
|
SET (ENV{LD_RUN_PATH} "$ORIGIN/../lib")
|
So this sort of works at run-time.
