cmake link library path

If you will not set it during configuration step via CMAKE_INSTALL_PREFIX ( -DCMAKE_INSTALL_PREFIX="/some/path" ), then CMake will set it to some system libraries path, which you might not want to use, especially if you are building your library for distribution. This creates the following CMake files that have the imported library information Semicolon-separated list of directories specifying a search path for the find_library() command. The find_library () command provides the full path, which can generally be used directly in calls to target_link_libraries () . Where the library name is the name of the shared library, minus the first lib part and minus the .so file extension. You'll need to remake them in your hash-config.cmake file using the install-time locations (which you can implement by doing a find_library ). Link a target to given libraries. find_library (FOO_LIB foo) CMake will figure out itself how the actual file name is. library RPATH resolution Code OlegWorld (Oleg Mironov) March 30, 2020, 1:23pm #1 Let's say we have a library A, which depends on library B. Library A is built using cmake and library B is linked to it publicly using target_link_libraries () Now i want to build an executable target, which depends on A, and B. set(CMAKE_LIBRARY_PATH path1 path2) find_library(NAMES gtest) What is target link libraries? My place is great for couples, solo guests, business travelers, and families (with kids). TARGET_LINK_LIBRARIES (middle_lib c:/users/oliver/tmp/cmake-dll/out/Debug/mylib.lib) and an executable to demonstrate it works The full path to the target's artifact will be quoted/escaped for the shell automatically. I would suggest adding a second library (shared or static) that links to it ADD_LIBRARY (middle_lib SHARED middle_lib.cpp) # hard-coded path is a bad idea outside an experiment. CMake is made to automatically search for the required include paths, library paths, and libraries to link to, per request in the CMakeLists.txt files. CMAKE_LIBRARY_PATH. If an imported library has the IMPORTED_NO_SONAME target property set, CMake may ask the linker to search for the library instead of using the full path (e.g. See the target_link_libraries () command for meaning of arguments. The solution is simple: When linking a shared library to your C application, you need to inform the GCC toolchain about the library you want to link. 12 Sept 2022 - Entire townhouse for 45. This command is rarely necessary and should be avoided where there are other choices. Let's say you have a library called libfoo located in /usr/local/lib and you want to link it with a node you're building called my_node. By default it is empty, it is intended to be set by the project. RPATH can also be useful during development, as you can link libraries within the build tree relative to the executable. Prefer to pass full absolute paths to libraries where possible, since this ensures the correct library will always be linked. By default it is empty, it is intended to be set by the project. Put the following in your CMakeLists.txt: # set the path to the library folder link_directories(/usr/local/lib) # link the libraries to the executable target_link_libraries (my_node foo) 0 answered Jul 9 '11 Anas 1 Like You already know the location of your library. target_link_libraries (pthread_task pthread.a libc.a) install (TARGETS pthread_task DESTINATION $ {CMAKE_INSTALL_PREFIX}) cmake command mkdir build cd build cmake -DCMAKE_BUILD_TYPE="DEBUG" -DCMAKE_C_FLAGS_DEBUG="-O0 -g -static" / env $ dpkg -l | grep cmake ii cmake 3.13.4-1 amd64 cross-platform, open-source make system $ uname -a The Variables I won't go into details about the following list of CMake variables related to RPATH. CMake doesn't know that these can be relocated. Firstly, the first parameter to add_library is the name of the library. When you install, your target will reference these imported targets. Specify libraries or flags to use when linking any targets created later in the current directory or below by commands such as add_executable () or add_library (). CMAKE_LIBRARY_PATH Semicolon-separated list of directories specifying a search path for the find_library () command. list (APPEND CMAKE_PREFIX_PATH "C:/TEMP/CMAKE-TEST/LIB-A/Win-VS2017") find_package (Lib_A_64 REQUIRED) target_link_libraries ($ {TARGET_NAME_LIBRARY} PUBLIC Lib_A_64) Notice that LIB-A is added as PUBLIC scope so that it will transitively link. It checks the usual places like /usr/lib, /usr/lib64 and the paths in PATH. My place is close to the beach and restaurants. Once you have located the library, add its full path to the Linked Libraries field under the VS properties for your main CMake target. find_library(NAMES gtest PATHS path1 path2 pathN) set the variable CMAKE_LIBRARY_PATH. Prefer to pass full absolute paths to libraries where possible, since this ensures the correct library will always be linked. This can be any valid CMake name, and the filename for the compiled library will be that value in your build directory. See also CMAKE_SYSTEM_LIBRARY_PATH and CMAKE_PREFIX_PATH. Note The target_link_libraries () command should be preferred whenever possible. The best way, IMO, is to make an IMPORTED target that represents these. Previous topic CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT Next topic CMAKE_LINK_DIRECTORIES_BEFORE "Mi casita de la playa" is a duplex located in front of the beach, where you will find an attractive and modern house to relax and enjoy one of the. Add it to the CMAKE_PREFIX_PATH when you call CMake, then CMake will look for your library in the passed paths, too. Concretely speaking there are two ways: designate the path within the command. You do this with linker flag: -l<library name>. /usr/lib/libfoo.so becomes -lfoo ). # enter your project directory $ cd myproject # it is always a good idea to not pollute the source with build files # so create a new build directory $ mkdir build $ cd build # run cmake and make $ cmake -DCMAKE_BUILD_TYPE=Release .. $ make # if you have tests, then the following $ ctest This has worked well for us on Linux and MacOS. See also CMAKE_SYSTEM_LIBRARY_PATH and CMAKE_PREFIX_PATH. set the variable CMAKE_LIBRARY_PATH set (CMAKE_LIBRARY_PATH path1 path2) find_library (NAMES gtest) the reason is as flowings: Note This command is rarely necessary and should be avoided where there are other choices. Oct 23, 2022 - Entire rental unit for $67. Look at the find_package () command and commands such as include_directories () and target_link_libraries (). if your library not found you may need to add directory, where library is located: link_directories( /home/user/blah ) # for specific path link_directories( ${CMAKE_CURRENT_BINARY_DIR} ) # if you put library where binary is generated How do I specify a library path in CMake? All i know about CMAKE is that is is a GUI with very limited options. CMake offers quite a few options to refine the behavior during build tree linking and install linking, as you will see below.
