在你的 `CMakeLists.txt` 文件中,你已经将 `include/header.h` 安装到了 `include` 目录中,但是在 `add_library` 命令中没有将该目录添加到编译器的 include 路径中,所以编译器无法找到该头文件。
你可以将 `target_include_directories` 命令添加到 `add_library` 命令中,这样就可以将 `include` 目录添加到编译器的 include 路径中了。修改后的代码如下所示:
```cmake
cmake_minimum_required(VERSION 3.16)
project(MyLib VERSION 1.0)
# 添加库代码文件到该库
add_library(mylib STATIC src/header.cpp)
target_include_directories(mylib
PUBLIC
$<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/include>
$<INSTALL_INTERFACE:include>
)
add_library(mylib_shared SHARED src/header.cpp)
target_include_directories(mylib_shared
PUBLIC
$<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/include>
$<INSTALL_INTERFACE:include>
)
# 指定install路径,以便于其他项目找到该库
install(TARGETS mylib mylib_shared
EXPORT MyLibTargets
ARCHIVE DESTINATION lib
LIBRARY DESTINATION lib
RUNTIME DESTINATION bin)
install(FILES include/header.h DESTINATION include)
# 生成MyLibConfig.cmake文件
include(CMakePackageConfigHelpers)
write_basic_package_version_file(
"${CMAKE_CURRENT_BINARY_DIR}/MyLibConfigVersion.cmake"
VERSION ${MyLib_VERSION}
COMPATIBILITY AnyNewerVersion
)
configure_package_config_file(
"${CMAKE_CURRENT_SOURCE_DIR}/MyLibConfig.cmake.in"
"${CMAKE_CURRENT_BINARY_DIR}/MyLibConfig.cmake"
INSTALL_DESTINATION cmake
)
install(
EXPORT MyLibTargets
NAMESPACE MyLib::
DESTINATION cmake
)
install(
FILES
"${CMAKE_CURRENT_BINARY_DIR}/MyLibConfig.cmake"
"${CMAKE_CURRENT_BINARY_DIR}/MyLibConfigVersion.cmake"
DESTINATION cmake
)
```
注意,在这里,我们使用了 `PUBLIC` 修饰符,将 include 路径添加到了 `mylib` 和 `mylib_shared` 目标的 include 路径中,这样在编译 `mylib` 和 `mylib_shared` 时都可以找到 `include/header.h` 头文件。
