Incompatibility with libtorrent-rasterbar 2.0

Trying to build the "feature/poconet_migration" branch on Arch. libtorrent-rasterbar version is 1:2.0.8-3. PKGBUILD contains the following build function:

build() {
  mkdir -p build
  cd build
  cmake "$srcdir/$_pkgname/" \
        -DCMAKE_INSTALL_PREFIX=/usr \
        -DCMAKE_CXX_STANDARD=14 \
        -DCMAKE_CXX_STANDARD_REQUIRED=ON \
        -DCMAKE_CXX_EXTENSIONS=OFF \
        -DWITH_DOCUMENTATION=ON \
        -DWITH_NLS=ON \
        -DWITH_CURL=ON \
        -DWITH_BITTORRENT=ON \
        -DWITH_WEBINTERFACE=ON
  make
}

Results in the following error:
