1. Clone wallet sources

git clone https://github.com/niobio-money/niobiomoney.git

2. Set symbolic link to coin sources at the same level as src. For example:

ln -s ../niobiomoney cryptonote

Alternative way is to create git submodule:

git submodule add https://github.com/niobio-money/niobiomoney.git cryptonote

3. Build

mkdir build && cd build && cmake .. && make
