The next release of the pvAccessCPP module injects a make variable*
$(EPICS_BASE_PVA_CORE_LIBS) meant to be used with the long existing
$(EPICS_BASE_IOC_LIBS).

eg. in the pva2pva module

> softIocPVA_LIBS += qsrv
> softIocPVA_LIBS += $(EPICS_BASE_PVA_CORE_LIBS)
> softIocPVA_LIBS += $(EPICS_BASE_IOC_LIBS)

At present this variable is defined as:

> EPICS_BASE_PVA_CORE_LIBS = pvAccessIOC pvAccessCA pvAccess pvData

For those following Git master, updating to the latest will make this
variable available.  Verify by looking for 'cfg/CONFIG_PVA_CORE' after
running 'make'.


* At least for versions of Base which support this.  For 3.14 series
this is >= 3.14.12.5, and for 3.15 series this is >= 3.15.2.  It may
work back as far as 3.14.10, but I haven't tested.
