问题描述
我们正在切换使用cmake，而我正在构建的应用程序之一使用了一个名为"debug"的库. (假设它位于/path/to/libdebug.so).
We are switching to use cmake, and one of the applications I'm building use a library called "debug". (Say it's located at /path/to/libdebug.so).
我意识到跟随调试不起作用是一个特殊的关键字.
I realized that following doesn't work as debug is a special keyword.
add_executable(myapp myapp.cpp)
target_link_libraries(myapp lib1 lib2 debug lib3)
这都不行，
add_executable(myapp myapp.cpp)
target_link_libraries(myapp lib1 lib2 lib3 debug)
因为它抱怨
在cmake中是否有任何解决方法?为了能够继续工作，我将libdebug.so复制到libdebug2.so，并针对debug2进行链接.但是我需要在cmake中找到一个长期解决方案，因为libdebug.so也被其他项目使用，我不能简单地更改其名称.
Is there any workaround for this in cmake? For now to be able to continue working, I copied libdebug.so to libdebug2.so and I'm linking against debug2. But I need to find a long-term solution in cmake as libdebug.so is used by other projects too and I can't simply change it's name.
推荐答案
另一种方法可能是为调试库创建 IMPORTED 目标:
Another approach could be creating IMPORTED target for debug library:
find_library(DEBUG_LIBRARY debug PATH <directory-contained-the-library> NO_DEFAULT_PATH)
add_library(debug_lib SHARED IMPORTED)
set_target_properties(debug_lib PROPERTIES IMPORTED_LOCATION ${DEBUG_LIBRARY})
此目标然后可用于与以下对象链接:
This target then may be used for link with:
target_link_libraries(myapp lib1 lib2 lib3 debug_lib)
尽管这种方法比使用完整的库名需要更多的行(和变量)，但它是平台无关的:CMake自动选择搜索的库扩展名.
While this approach requires more lines (and variables) than using full library name, it is platform independent: extension of the library searched is choosen automatically by CMake.
