Created a PKGBUILD for Archlinux; need help to make it 3rd party independent

[alkavan]

Here's the PKGBUILD file for the master branch:

pkgname=theiasfm-git
_gitname='TheiaSfM'
_gitbranch="master"
pkgver=0.8
pkgrel=1
pkgdesc='Theia is an end-to-end structure-from-motion library that was created by Chris Sweeney.'
arch=('i686' 'x86_64')
url='http://www.theia-sfm.org/'
license=('BSD')
depends=('rocksdb')
makedepends=('git' 'gcc' 'cmake')
source=("https://github.com/sweeneychris/${_gitname}/archive/${_gitbranch}.zip")
md5sums=('SKIP')

#prepare() {}

build() {
  cd "${srcdir}"
  mkdir -p theiasfm_build
  cd theiasfm_build
  cmake ../TheiaSfM-master/
  make
}

package() {
  cd "${srcdir}/theiasfm_build"
  make DESTDIR="$pkgdir" install
}

The only dependency I needed to build was depends=('rocksdb') but it's not all of them, need help to complete... there is also an issue with the 3rd party libraries: /pkg/theiasfm-git/usr/local/include contains: cereal flann gtest theia So cereal can be replaced with aur/cereal 1.2.2-3 ? flann can be replaced with aur/flann 1.9.1-3 ? And gtest with community/gtest 1.8.1-3 ?

Does anyone have a need for this? And perhaps can help to make it dep. complete and clean?
