Where the executables are, but minus the bin/$(T_A) subdirectory. In other 
words, to the $(INSTALL_LOCATION) of the sequencer (which defaults to the 
source top-level directory).

No need to do that, there is special code in teh EPICS base rules to include 
relevant stuff under $(SNCSEQ)/configure. Typically all you need is to add

<lib-or-exe-name>_SRCS += my-state-machine.st

'makeBaseApp.pl -t example' will give you an example setup and it includes a 
state machine.
