本文介绍了获取 CMake 错误:无法为不是由项目构建的目标指定链接库的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在我的代码中实现 CMake,但出现错误
I am implementing CMake in my code but I'm getting the error
无法为不是由项目构建的目标Qt5::Widgets"指定链接库".
"Cannot specify link libraries for target "Qt5::Widgets" which is not built by the project".
以下是 CMakeLists.txt 的内容:
Below are the contents of the CMakeLists.txt:
#Specify the version being used aswell as the language
cmake_minimum_required(VERSION 2.6)
#Name your project here
project(eCAD)
#Sends the -std=c++11 flag to the gcc compiler
ADD_DEFINITIONS(-std=c++11)
#This tells CMake to main.cpp and name it eCAD
add_executable(eCAD main.cpp)
#include the subdirectory containing our libs
add_subdirectory (gui)
include_directories(gui)
#include Qt directories
find_package(Qt5Widgets)
find_package(Qt5Core)
find_package(Qt5Designer)
SET(QT_USE_QTDESIGNER ON)
#link_libraries
target_link_libraries(Qt5::Widgets Qt5::Core)
推荐答案
target_link_libraries
的第一个参数是目标名称:
The first argument of target_link_libraries
is the target name:
target_link_libraries(eCAD Qt5::Widgets Qt5::Core)
