A simple example that demonstrats how to make use of unordered_dense with cmake.

Use globally installed unordered_dense:

mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX:PATH=${HOME}/unordered_dense_install ..
make

Use locall installed unordered_dense, as in the main README.md:

mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX:PATH=${HOME}/unordered_dense_install ..
make
