To build this project, you need

• GNU compiler version >4.9.2 with g++ and gfortran
• cmake version >3.0

Then do a standard out-of-source build by executing the following inside the projects directory:

mkdir build
cd build
cmake ..
make

You'll find a library called libaplcon++.so inside the above created build directory, the corresponding header to include is src/APLCON.hpp.

You can build benchmarking binaries by calling cmake -DEnableBenchmark=On .. and running ./bench/bench_APLCON. Tests are build and run by make build_and_test.
