我在官网下的bin安装包，安装时有这么一句话
If you're using QtOpenGL, you'll also need OpenGL development files. You can use the following command to find out which packages to install:
sudo apt-get install libgl-dev libglu-dev
我终端输如后提示
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libgl-dev is a virtual package provided by:
libgl1-mesa-swx11-dev 7.7.1-1ubuntu3
libgl1-mesa-dev 7.7.1-1ubuntu3
You should explicitly select one to install.
E: Package libgl-dev has no installation candidate
libgl1-mesa-swx11-dev 7.7.1-1ubuntu3
libgl1-mesa-dev 7.7.1-1ubuntu3
这两个有什么区别，我该装哪个？
