[yocto] openjpeg on github

[Edward Vidal]

Hello All,When a project is using git instead of tar file which branch is used?Is best to be using git or tar file with yocto?
Openjepeg is now on github.   The openjpeg 2.1.0 was at SRC_URI = "${SOURCEFORGE_MIRROR}/project/${BPN}.mirror/${PV}/${BPN}-${PV}.tar.gz".   I did the following to create a new recipe.
recipetool create  -o /home/vidal/wkg/yocto/RaspberryPi2/poky/meta-oe/recipes-graphics/openjpeg/openjpeg_git.bb https://github.com/uclouvain/openjpeg.git
 # Recipe created by recipetool
# This is the basis of a recipe and may need further editing in order to be fully functional.
# (Feel free to remove these comments when editing.)
#
# Unable to find any files that looked like license statements. Check the accompanying
# documentation and source headers and set LICENSE and LIC_FILES_CHKSUM accordingly.
#
# NOTE: LICENSE is being set to "CLOSED" to allow you to at least start building - if
# this is not accurate with respect to the licensing of the software being built (it
# will not be in most cases) you must specify the correct value before using this
# recipe for anything other than initial testing/development!
LICENSE = "CLOSED"
LIC_FILES_CHKSUM = ""

SRC_URI = "https://github.com/uclouvain/openjpeg.git"
SRC_URI[md5sum] = "9ad2bb8d9e833bfd74b4885a0f1d3882"
SRC_URI[sha256sum] = "af9d33bcc1485f1938ceb13464e66041dc4538dccc8edf02320141b0da9f95c6"
inherit cmake

DEPENDS = "libpng tiff lcms"
# NOTE: no Makefile found, unable to determine what needs to be done

do_configure () {
    # Specify any needed configure commands here
        mkdir build
}

do_compile () {
    # Specify compilation commands here
        cd build
        cmake ../
}

do_install () {
    # Specify install commands here
}
When I try bitbake openjpeg I get several errors.
The INSTALL file Using cmake (see www.cmake.org)

Type:
  cmake .
  makeOn my system I created a buildcd build 
cmake ../makeThis builds okay.
Any and all help  is appreaciated.Cheers
