[yocto] if else blocks in recipes(bitbake)

[S.Jaritz at esa-grimma.de]

Hej

If have a simple problem. On one system a program is started as a daemon 
and on the other one not. In my recipe the program is build. by using 
update-rc.d I create the init script for systemV. The code looks like:
##########
SUMMARY = "myApp"
SECTION = "myApp"
LICENSE = "CLOSED"

DEPENDS = "dbus glibmm libsigc++-2.0 libconfig"
RDEPENDS_${PN} = "bash initscripts"

inherit cmake update-rc.d

SRCREV = "${AUTOREV}"
SRC_URI = "gitsm://myServer/myApp;protocol=http;branch=develop"

PVBASE := "${PV}"
PV = "${PVBASE}.${SRCPV}"

S = "${WORKDIR}/git/"

INITSCRIPT_PARAMS = "start 95 2 3 4 5 . stop 01 0 1 6 ."
INITSCRIPT_NAME = "myAppD.sh"

CONFFILES_${PN} += "${sysconfdir}/init.d/myAppD.sh"
##########
Would like to that(pseudo-code):
##########
BUILDVAR = "yes"

if BUILDVAR == "yes" then
        INITSCRIPT_PARAMS = "start 95 2 3 4 5 . stop 01 0 1 6 ."
        INITSCRIPT_NAME = "myAppD.sh"
 
        CONFFILES_${PN} += "${sysconfdir}/init.d/myAppD.sh"
endif
##########

How to tell this bitbake? 

Regards!
