包的文件目录如图所示,├── include │ └── header.h └── lib ├── cmake │ └── MyPackage │ ├── MyPackageConfig.cmake │ └── MyPackageTargets.cmake └── libmylib.a,那么MyPackageTargets.cmake应该如何设置INTERFACE_LINK_LIBRARIES
时间: 2024-01-26 17:03:18 浏览: 94
假设libmylib.a是MyPackage库所依赖的库,那么MyPackageTargets.cmake中的INTERFACE_LINK_LIBRARIES属性应该设置为:
```
set_target_properties(MyPackage::MyPackage PROPERTIES
INTERFACE_LINK_LIBRARIES "/path/to/lib/libmylib.a"
)
```
其中/path/to/lib/libmylib.a是实际的库文件路径。

pkg_test文件夹下的目录如下├── cmake │ ├── MyLibConfig.cmake │ └── MyLibConfigVersion.cmake ├── include │ └── header.h └── lib ├── libmylib.a └── libmylib_shared.so,切该目录已经包含在CMAKE_PREFIX_PATH下,为什么其他cmake文件提醒[cmake] Could not find a package configuration file provided by "MyLib" with any of [cmake] the following names: [cmake] [cmake] MyLibConfig.cmake [cmake] mylib-config.cmake
出现这个问题的原因可能是CMake没有正确设置CMAKE_PREFIX_PATH变量,或者CMake缓存没有被正确地重新生成。
首先,确保CMAKE_PREFIX_PATH变量包含了pkg_test文件夹的路径。可以在CMakeLists.txt文件中添加以下行来设置CMAKE_PREFIX_PATH:
```
set(CMAKE_PREFIX_PATH "/path/to/pkg_test:${CMAKE_PREFIX_PATH}")
```
如果CMAKE_PREFIX_PATH已经正确设置,那么可能是CMake缓存没有正确地更新。可以尝试清除CMake缓存并重新生成:
```
rm -rf CMakeCache.txt
mkdir build
cd build
cmake ..
```
如果问题仍然存在,那么可以尝试手动指定MyLibConfig.cmake的路径。可以在CMakeLists.txt文件中添加以下行:
```
find_package(MyLib CONFIG REQUIRED PATHS "/path/to/pkg_test/cmake")
```
这将强制CMake在指定的路径中搜索MyLibConfig.cmake文件。
记住cmake代码cmake_minimum_required(VERSION 3.16) # 声明该项目的名称和版本号 project(MyLib VERSION 1.0) # 添加库代码文件到该库 add_library(mylib STATIC src/header.cpp) add_library(mylib_shared SHARED src/header.cpp) include_directories(include) # 指定install路径,以便于其他项目找到该库 install(TARGETS mylib mylib_shared EXPORT MyLibTargets ARCHIVE DESTINATION lib LIBRARY DESTINATION lib RUNTIME DESTINATION bin) install(FILES include/header.h DESTINATION include) # 生成MyLibConfig.cmake文件 include(CMakePackageConfigHelpers) write_basic_package_version_file( "${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 # ) export(EXPORT MyLibTargets NAMESPACE MyLib:: FILE MyLibTargets.cmake) install(FILES ${CMAKE_CURRENT_BINARY_DIR}/MyLibTargets.cmake DESTINATION cmake) install( FILES "${CMAKE_CURRENT_BINARY_DIR}/MyLibConfig.cmake" "${CMAKE_CURRENT_BINARY_DIR}/MyLibConfigVersion.cmake" DESTINATION cmake ),并在/home/czl/cmake_lib/build目录下执行命令cmake .. -DCMAKE_INSTALL_PREFIX=/home/czl/pkg_test,并告诉我生成的MyLibTargets.cmake文件中,静态库的引用路径是什么
生成的MyLibTargets.cmake文件中,静态库的引用路径是:
```
target_link_libraries(MyLib::mylib INTERFACE
$<BUILD_INTERFACE:${CMAKE_CURRENT_LIST_DIR}/../lib/libmylib.a>
$<INSTALL_INTERFACE:lib/libmylib.a>
)
```
其中,`$<BUILD_INTERFACE>`指的是在构建项目时引用的路径,`$<INSTALL_INTERFACE>`指的是在安装项目后引用的路径。在这个例子中,静态库`libmylib.a`在构建项目时的路径为`${CMAKE_CURRENT_LIST_DIR}/../lib/libmylib.a`,在安装项目后的路径为`lib/libmylib.a`。
