How to Run Cpp-tests on Linux

Overview##

The document will show you how to compile & run cpp-tests on Linux.
In the document, the variable cocos2dx_root means the root path of cocos2d-x.

The document is suitable for version v3.0rc or newer.

Install Dependences

The dependenced libraries are:
```
  libx11-dev
  libxmu-dev
  libglu1-mesa-dev
  libgl2ps-dev
  libxi-dev
  g++
  libzip-dev
  libpng12-dev
  libcurl4-gnutls-dev
  libfontconfig1-dev
  libsqlite3-dev
  libglew*-dev
  libssl-dev
```
If you are using Ubuntu/Debian, there is a shell script (build/install-deps-linux.sh) for you to install the dependences easily. Run commands below in terminal:
```
  $ cd $cocos2dx_root/build
  $ ./install-deps-linux.sh
```
Otherwise, you should install the depences by yourself.
Generate makefile

After the dependened libs are installed, run cmake to generate makefile:
```
  $ mkdir linux-build
  $ cd linux-build
  $ cmake ../..
```
When cmake returns correctly, many files & folders will be generated in coocs2dx_root/build/linux-build:
Compiling

Run make to compile
```
  $ make
```
Application will be generated in cocos2dx_root/build/linux-build/bin/cpp-tests/ if compile correctly.
Run cpp-tests
```
  $ cd bin/cpp-tests/
  $ ./cpp-tests
```
You will see the application is running like this:
