我想在Clion中通过cmake添加glfw依赖项，但我收到奇怪的错误，这是CMakeLists.txt

cmake_minimum_required(VERSION 3.17)
project(hello_gl)

set(CMAKE_CXX_STANDARD 14)

find_package(glfw3 3.3 REQUIRED)

target_link_libraries(hello_gl glfw)


add_executable(hello_gl main.cpp)

CMake Error at CMakeLists.txt:8 (target_link_libraries):
Cannot specify link libraries for target "hello_gl" which is not built by
this project.

这就是我收到的错误？为什么cmake找不到我的应用程序？

推荐答案

在添加可执行文件后尝试链接glfw lib时，它起作用

cmake_minimum_required(VERSION 3.17)
project(hello_gl)

set(CMAKE_CXX_STANDARD 14)

add_executable(hello_gl main.cpp)

find_package(glfw3 3.3 REQUIRED)

target_link_libraries(hello_gl glfw)

这里是正确的CMakeLists.txt
