添加安装前缀“Qt5Widgets”到CMAKE_PREFIX_PATH [英] Add the installation prefix of "Qt5Widgets" to CMAKE_PREFIX_PATH

问题描述

我不知道很多关于cmake，我试图构建一个客户端使用cmake和Qt。获取以下错误：

I don't know a lot about cmake, I'm trying to build a client using cmake and Qt. Getting the following error:

CMake错误at alethzero / CMakeLists.txt：26（find_package）：由
提供FindQt5Widgets .cmake在CMAKE_MODULE_PATH这个项目

已要求CMake找到由

Qt5Widgets提供的包配置文件，但CMake没有找到一个。

CMake Error at alethzero/CMakeLists.txt:26 (find_package): By not providing "FindQt5Widgets.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"Qt5Widgets", but CMake did not find one.

无法使用以下任何名称找到Qt5Widgets
提供的程序包配置文件：

Could not find a package configuration file provided by "Qt5Widgets" with any of the following names:

Qt5WidgetsConfig.cmake
qt5widgets-config.cmake

添加安装前缀的Qt5Widgets到CMAKE_PREFIX_PATH或
将Qt5Widgets_DIR设置为包含上述
文件之一的目录。如果Qt5Widgets提供单独的开发包或
SDK，请确保它已安装。

Add the installation prefix of "Qt5Widgets" to CMAKE_PREFIX_PATH or set "Qt5Widgets_DIR" to a directory containing one of the above files. If "Qt5Widgets" provides a separate development package or SDK, be sure it has been installed.

- 配置不完整，

-- Configuring incomplete, errors occurred!

据我所知，我需要添加QT路径到CMake。我该怎么做？我有Qt安装在/ home / user / Programs。我发现的所有解释都是只做这个或那个。我需要确切的终端命令，所以我可以只是学会如何做到在未来。

As far as I understand, I need to add the QT path to CMake. How do I do it? I have Qt installed in /home/user/Programs. All the explanations I find are "just do this or that". I need the exact Terminal commands so I can just learn how to do it in the future.

谢谢！

更新： export CMAKE_PREFIX_PATH = / home / user / Programs 没有帮助我。

推荐答案

这是有记录的：

This is documented:

http://doc.qt.io/qt-5/cmake-manual.html

The easiest way to use CMake is to set the CMAKE_PREFIX_PATH 
environment variable to the install prefix of Qt 5

做这个

export CMAKE_PREFIX_PATH=/home/user/Programs/<other_stuff>

其中引用编译器等，以使此完整路径有效：

where references the compiler etc, so that this complete path is valid:

/home/user/Programs/<other_stuff>/bin/qmake*
