如何使用cmake查找库？

发布于 2024-09-12 11:41:17 字数 656 浏览 2 评论 0原文

要将可执行文件与驻留在标准位置的库链接，可以在 CmakeLists.txt 文件中执行以下操作：

create_executable(generate_mesh generate_mesh.cpp)
target_link_libraries(generate_mesh OpenMeshCore)

如果要链接的库放置

/usr/local/lib/libOpenMeshCore.dylib

在在

/usr/local/lib/OpenMesh/libOpenMeshCore.dylib

如何指定 target_link_libraries 应该真正链接到放置在 sibdirectory 中的库？我想知道 target_link_libraries 有一些有用的选项，可以指定该库位于标准位置的子目录中，例如，

target_link_libraries(generate_mesh OpenMesh/OpenMeshCore)

如果不可能，是否有办法使用 find_library 来搜索 /usr/local/lib< /code> 递归地，包括它的子目录，对于给定的库文件？

To link an executable with a library that resides in a standard location, one can do the following in a CmakeLists.txt file:

create_executable(generate_mesh generate_mesh.cpp)
target_link_libraries(generate_mesh OpenMeshCore)

This would work if the library, that is being linked against, was placed in

/usr/local/lib/libOpenMeshCore.dylib

However, in this case the library resides under

/usr/local/lib/OpenMesh/libOpenMeshCore.dylib

How can I specify that target_link_libraries should really link against a library placed in a sibdirectory? I wonder there is some useful option to target_link_libraries that would specify that the library is in a subdirectory in a standandard location, e.g.

target_link_libraries(generate_mesh OpenMesh/OpenMeshCore)

If that is not possible, is there a way to use find_library to search /usr/local/lib recursively, including its sub-directories, for the given library file?

您可以将不同的目录添加到find_library。要使用此库，请通过 cmake -DFOO_PREFIX=/some/path ... 调用 cmake。

find_library( CPPUNIT_LIBRARY_DEBUG NAMES cppunit cppunit_dll cppunitd cppunitd_dll
            PATHS   ${FOO_PREFIX}/lib
                    /usr/lib
                    /usr/lib64
                    /usr/local/lib
                    /usr/local/lib64
            PATH_SUFFIXES debug )

find_library( CPPUNIT_LIBRARY_RELEASE NAMES cppunit cppunit_dll
            PATHS   ${FOO_PREFIX}/lib
                    /usr/lib
                    /usr/lib64
                    /usr/local/lib
                    /usr/local/lib64
            PATH_SUFFIXES release )

if(CPPUNIT_LIBRARY_DEBUG AND NOT CPPUNIT_LIBRARY_RELEASE)
    set(CPPUNIT_LIBRARY_RELEASE ${CPPUNIT_LIBRARY_DEBUG})
endif(CPPUNIT_LIBRARY_DEBUG AND NOT CPPUNIT_LIBRARY_RELEASE)

set( CPPUNIT_LIBRARY debug     ${CPPUNIT_LIBRARY_DEBUG}
                    optimized ${CPPUNIT_LIBRARY_RELEASE} )

# ...
target_link_libraries(foo ${CPPUNIT_LIBRARY})

You can add different directories to find_library. To use this library call cmake by cmake -DFOO_PREFIX=/some/path ....

find_library( CPPUNIT_LIBRARY_DEBUG NAMES cppunit cppunit_dll cppunitd cppunitd_dll
            PATHS   ${FOO_PREFIX}/lib
                    /usr/lib
                    /usr/lib64
                    /usr/local/lib
                    /usr/local/lib64
            PATH_SUFFIXES debug )

find_library( CPPUNIT_LIBRARY_RELEASE NAMES cppunit cppunit_dll
            PATHS   ${FOO_PREFIX}/lib
                    /usr/lib
                    /usr/lib64
                    /usr/local/lib
                    /usr/local/lib64
            PATH_SUFFIXES release )

if(CPPUNIT_LIBRARY_DEBUG AND NOT CPPUNIT_LIBRARY_RELEASE)
    set(CPPUNIT_LIBRARY_RELEASE ${CPPUNIT_LIBRARY_DEBUG})
endif(CPPUNIT_LIBRARY_DEBUG AND NOT CPPUNIT_LIBRARY_RELEASE)

set( CPPUNIT_LIBRARY debug     ${CPPUNIT_LIBRARY_DEBUG}
                    optimized ${CPPUNIT_LIBRARY_RELEASE} )

# ...
target_link_libraries(foo ${CPPUNIT_LIBRARY})
