How to build DCA++ on ORNL's Summit supercomputer

Clone the DCA++ repository to obtain the latest version of the master branch:
```
 $ git clone https://github.com/CompFUSE/DCA.git dca_source
```

Load all required modules:

 $ source dca_source/build-aux/summit_load_modules.sh

Create a clean build directory and change to it:
```
 $ mkdir build_summit && cd build_summit
```
Use CMake to configure the build and generate the build files:
```
 $ cmake -C ../dca_source/build-aux/summit.cmake -DCMAKE_BUILD_TYPE=Release ../dca_source
```
Note that setting CMAKE_BUILD_TYPE to Release adds compiler optimization flags that we want for production builds.
Compile the applications:
```
 $ make -j 16
```
