Vala: Compiling with libsecret

The package name is "libsecret-1 ". You can use it like this in your Makefile.am file:

AM_VALAFLAGS = \
	--pkg=libsecret-1

Some parts of the libsecret API are not yet stable. To use them you need to define the SECRET_WITH_UNSTABLE C preprocessor macro to use them, or else the build will fail:

AM_CPPFLAGS = \
	-DSECRET_WITH_UNSTABLE=1
