C ++：找不到静态链接

Question

我用cmake创建一个libtest_lib.a文件。

cmake_minimum_required(VERSION 3.8)
project(test)
set(CMAKE_CXX_STANDARD 98)
set(SOURCE_FILES library.cpp library.h)
add_library(test_lib ${SOURCE_FILES})

然后在我的可执行C ++项目中，我包含了#include "library.h" 和CMakeList.txt：

cmake_minimum_required(VERSION 3.8)
project(study)
set(CMAKE_CXX_STANDARD 98)
set(SOURCE_FILES main.cpp)
add_executable(study ${SOURCE_FILES})
target_link_libraries(study libtest_lib.a) //libtest_lib.a file under the project path

但它失败了。

/Users/bin381/CLionProjects/study/main.cpp:1:10: fatal error: 'library.h' file not found

Answer 1

请添加文档中提到的include目录：https://cmake.org/cmake/help/v3.0/command/include_directories.html 否则，cmake将无法找到包含文件的位置。
