 ## Remarks
 Even if designed with portability in mind, all libraries were developed with Visual Studio 2015 and tested on Windows platform (a porting to other platforms should be a nice contribution).

 Libraries and their test projects are separated, so you can use the libraries without getting [Google C++ Testing Framework].
 
+If you don't want or cannot use the distribution provided with the releases you can follow the procedure described hereafter.

 In the `depend` folder you must put a distribution of the external libraries used: [Google C++ Testing Framework], [boost] and [rapidjson]. Include files of [Google C++ Testing Framework] must be put in `depend/boost/` (e.g. `depend/boost/boost/`). Compiled binaries of [Google C++ Testing Framework] must be put in a proper subfolder of `depend/googletest/lib/` folder (e.g. `gtest.lib` and `gtestd.lib` in `depend/googletest/lib/VC140-x64/` and `depend/googletest/lib/VC140-x86/` for Visual Studio 2015 with 64 and 32 bit platforms). For [boost] libraries include files must be put in `depend/boost/` (e.g. `depend/boost/boost/`) and compiled binaries must be put in `depend/boost/lib/` folder. For [rapidjson] library include files must be put in `depend/rapidjson/` (e.g. `depend/rapidjson/rapidjson/`)
 
 You can change this configuration editing the property sheeets (`*.props` files) in `gpvulc/projects/vs2015/` and in `gpvulc-tests/` (remember to change also the `BOOST_VER` variable, if needed).
