build errors using gcc10 on rhel7 with cuda disabled

[cwsmith]

on cranium rhel7

env:

module purge
module unuse /opt/scorec/spack/lmod/linux-rhel7-x86_64/Core
module use /opt/scorec/spack/v0154_2/lmod/linux-rhel7-x86_64/Core
module load gcc mpich simmetrix-simmodsuite/16.0-210202dev cmake
export MPICH_CXX=g++

config:

cmake $1 \
-DCMAKE_INSTALL_PREFIX=$PWD/install \
-DBUILD_SHARED_LIBS=OFF \
-DOmega_h_USE_MPI=on \
-DCMAKE_CXX_COMPILER=`which mpicxx`

there are multiple errors - the following appears to be a problem with the lambda syntax
