Yes, correct.

For BESSY we have been using our own rules for a long time, and
something we added there was

# GENERIC_INSTALL_RULE should be called with 3 or 4 arguments:
# $1 extension
# $2 description of file type
# $3 where to install
# $4 (optional) extra vpath dirs
define GENERIC_INSTALL_RULE
vpath %.$1 $(USR_VPATH) $(GENERIC_SRC_DIRS) $4 $(COMMON_DIR)
$3/%.$1: %.$1
        $(ECHO) "Installing $2 file $$(@F)"
        @$$(INSTALL) -d -m 644 $$< $$(@D)
endef

so you can add the rules to install other file types by using the macro
like (example for .proto files, we actually added ~10 files types we may
want to install)

$(eval $(call
GENERIC_INSTALL_RULE,proto,protocol,$(INSTALL_DB),$(RELEASE_DBSEARCHDIRS)))

The 4th argument sets the search path to the db dirs of all modules in
RELEASE, so after adding this block to the rules, a definition in you
App's Makefile

DB_INSTALLS += xxx.proto

will look for xxx.proto in the db subdirectories of all modules defined
in RELEASE files.
