ubuntu 安装QT5

参考：https://blog.youkuaiyun.com/wuweifeng_2017/article/details/78322249，完成安装和配置

注意

1 路径配置

在命令端口中输入命令：sudo vim /usr/lib/x86_64-linux-gnu/qt-default/qtchooser/default.conf  打开default.conf文件。

将第一行改为自己安装路径（这是我的安装路径/home/wwf/software/Qt5.8.0）下的bin目录的路径，第二行改为Qt5.8.0目录的路径。

2 安装 libgl1-mesa-dev

在命令端口中输入命令：sudo apt-get install libgl1-mesa-dev 进行安装。

3 另外有个问题

CMake Error at CMakeLists.txt:20 (find_package):

  By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has

  asked CMake to find a package configuration file provided by "Qt5Core", but

  CMake did not find one.

 

  Could not find a package configuration file provided by "Qt5Core" with any

  of the following names:

 

    Qt5CoreConfig.cmake

    qt5core-config.cmake

 

  Add the installation prefix of "Qt5Core" to CMAKE_PREFIX_PATH or set

  "Qt5Core_DIR" to a directory containing one of the above files.  If

  "Qt5Core" provides a separate development package or SDK, be sure it has

  been installed.
