By default, the OpenFHE and HEXL libraries are built and installed at openfhe-configurator/openfhe-staging/install.
If you want to change the install location, pass an OPENFHE_INSTALL_DIR value to the build script e.g.,
% OPENFHE_INSTALL_DIR=~/local scripts/build-openfhe-development.sh
If you want to change OpenFHE build paramaters, pass those changes as CMAKE_FLAGS e.g.,
% CMAKE_FLAGS="-DWITH_OPENMP=OFF -DCMAKE_BUILD_TYPE=Debug" scripts/build-openfhe-development.sh
If you want to use a preinstalled build of the Intel HEXL library with your openfhe-hexl build, include the following:
% CMAKE_FLAGS="-DINTEL_HEXL_PREBUILT=ON -DINTEL_HEXL_HINT_DIR=[PATH TO INTEL HEXL]" scripts/build-openfhe-development.sh
