ubuntu18.04 編譯qt-vlc qt5.12.3

1.源碼下載，參考vlc-qt源碼目錄裏面有README.md和BUILDING.md

git clone git://github.com/vlc-qt/vlc-qt.git
git submodule init
git submodule update

2.編譯源碼，BUILDING.md裏面找到linux編譯源碼流程

### Linux
Install requirements from your distribution's repository.
Supported generators are `make` and `ninja`.

Make example:
```
$ mkdir build
$ cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Debug
$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/libvlc-qt  #(vlc-qt的安裝目錄，這句是筆者加的)
$ make -j8
$ make install
```

3.下載qt-vlc運行demo

git clone https://github.com/vlc-qt/examples.git

4.編譯vlc-qt/examples

1.刪除多餘文件
使用cmake, rm simple-player.pro  src/src.pro
If you want to use CMake, you can delete
simple-player.pro
src/src.pro

使用qmake, rm CMakeLists.txt cmake/* src/CMakeLists.txt -rf
If you want to use qmake, you can delete
CMakeLists.txt
cmake/*
src/CMakeLists.txt


2.配置pro文件
# Edit below for custom library location
LIBS       += -L/usr/local/libvlc-qt/lib -lVLCQtCore -lVLCQtWidgets
INCLUDEPATH += /usr/local/libvlc-qt/include

5.運行效果如下：
