我用Cmake做project，生成的时候报错：Target "xxxxxxx" links to: igl::core, but the target was not found

Question

Configuring done
CMake Error at CMakeLists.txt:5 (target_link_libraries):
  Target "101_GlyphRendering_bin" links to:

    igl::core

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

这是我的CMakeLists.txt ：

cmake_minimum_required(VERSION 3.16)
project(101_GlyphRendering)

add_executable(${PROJECT_NAME}_bin main.cpp)
target_link_libraries(${PROJECT_NAME}_bin PUBLIC igl::core igl::glfw igl::opengl tutorials)

我打开项目并构建它，出现错误：

C1083 Cannot open include file:'directional/directional_viewer.h':No such file or dictory

在此处输入图像描述

Answer 1

我不确定你的问题到底是什么，但说到

C1083 无法打开包含文件：'directional/directional_viewer.h'：没有这样的文件或目录

如果要手动链接库，还需要包含该库的标头。 为此，请使用

target_include_directories(<target> PUBLIC <include_folder_dir>)

其中<target>是您的${PROJECT_NAME}_bin和<include_folder_dir>是包含您链接到的库标题的文件夹。
