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
