 ### Build NetLincesing-cpp
 1. Download the latest release and unpack to `NetLicensingClient-cpp` (or checkout [master](https://github.com/Labs64/NetLicensingClient-cpp.git) to build the latest development version)
 2. Install **curl** (for development, including C headers and libraries). E.g. in **Ubuntu**:
-    ```sudo apt-get install libcurl4-openssl```

 Unit tests require [**Boost**](https://www.boost.org) Unit Test Framework. To build project with the unit tests activated add cmake option `-DBUILD_TESTS=yes`. The tests must be executed from `tests/` subdirectory on Linux or `tests\Debug\` on Windows in order to properly locate the JSON files with test data.
