INSTALL (
	FILES ${CMAKE_CURRENT_SOURCE_DIR}/sample_features
	DESTINATION etc
	RENAME features
)

Using that, if "etc/features" exists and I run "make install" features 
gets overwritten every time.

$ file etc/features
etc/features: ASCII English text

$ echo "XXXXXXXXX" >> etc/features
$ grep "XXXXXXXXX" etc/features
XXXXXXXXX

$ cd path/in-source/build
$ make install

$ grep "XXXXXXXXX" etc/features
$ echo $?
1

Here is the Makefile login I'm attempting to mimic:

	if [ ! -f $(DESTDIR)$(SYSCONFDIR)/features ]; then \
		$(INSTALLDATA) ${srcdir}/sample_features	$(DESTDIR)$(SYSCONFDIR)/features ; \
	fi
