CMAKE GLFW 链接问题

Question

我想在 CLion 中通过 cmake 添加 glfw 依赖项，但出现奇怪的错误，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.

这是我得到的错误？为什么cmake找不到我的app？

Answer 1

当我在添加可执行文件

后尝试linkglfw lib时，它起作用了

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)

这里是对的CMakeLists.txt
