Thanks for the quick response, I will be happy if you can help me solve 
this, since it's the last stone in our shoes before we go all in on yocto.


My target (at this time) is just a plain vanilla X86 platform - i might 
change in the furture.
The recipes that cause troubles, are those who examine my git repos
one example, I have several made from this template ($BRANCH is set by 
envoking scripts):

/DESCRIPTION = "Reflector deamon-  from local GIT"//
//# The initscript reflectord.sh that starts the deamon is installed 
with basic-framwork-files//
//HOMEPAGE = "www.visionweeding.com"//
//LICENSE = "CLOSED"//
//FPE_PATH = "/opt/fpe"//
//BRANCH ?="develop"//
//SRC_URI = 
"git:///eserver/GIT/autodiscover/;branch=${BRANCH};;name=discover " //
//SRCREV_discover= "${AUTOREV}"//
//SRCREV_FORMAT= "discover"//
//PV = "1.0.0+gitr${SRCPV}"//
//S = "${WORKDIR}/git"//
//inherit cmake//
//FILESEXTRAPATHS_prepend := "${THISDIR}/files:"//
//FILES_${PN} += "${FPE_PATH}/bin/reflectord \//
//        ${FPE_PATH}/bin/SearchBeam \//
//  "//
//do_install_append() {//
//
//    bbnote "Branch test BRANCH= ${BRANCH}"//
////
//      install -d ${D}${FPE_PATH}/bin//
////
//    rm  -rf ${FPE_PATH}/bin/.debug/*//
//    install -d ${D}${sysconfdir}/init.d //
//    install -m 0755 ${WORKDIR}/SearchBeam ${D}${FPE_PATH}/bin //
//    install -m 0755 ${WORKDIR}/reflectord ${D}${FPE_PATH}/bin//
////    }//
//
