simply write a recipe for your app and let the build system build
your application.

The recipe can be quite simple if your app doesn't depends on other
libs than qt4 :

DESCRIPTION =3D "Application QT4-X11"
SECTION =3D "Apps"
LICENSE =3D "yourlicense"
LIC_FILES_CHKSUM =3D "file://youlicense;md5=3Dyourmd5"

inherit qt4x11

SRC_URI =3D "file://application.tar.bz2"
# or directly download it from a VCS

# may be necessary :
EXTRA_QMAKEVARS_PRE +=3D "PREFIX=3D/usr"
EXTRA_OEMAKE +=3D "INSTALL_ROOT=3D${D}"

do_install() {
	oe_runmake install INSTALL_ROOT=3D${D}
}
