CMAKE_<LANG>_LINK_LIBRARY_FLAG — CMake 3.23.0-rc1 Documentation CMAKE_<LANG>_LINK_LIBRARY_FLAG ¶ New in version 3.16. Flag to be used to link a library into a shared library or executable. This flag will be used to specify a library to link to a shared library or an executable for the specific language. On most compilers this is -l.

PUBLIC doesn't mean much for an executable; for a library it lets CMake know that any targets that link to this target must also need that include directory ...

22.03.2022 · In CMake you could use find_package to find libraries you need. There usually is a FindBoost.cmake along with your CMake installation.. As far as I remember, it will be installed to /usr/share/cmake/Modules/ along with other find-scripts for common libraries. You could just check the documentation in that file for more information about how it works.

Linking CMake Libraries To Other C++ Targets Now that you can create library targets with CMake, the next reasonable step is to use them in your programs! Linking library targets to other targets — whether it’s an executable or another library target — is easy with CMake.

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 (). See the target_link_libraries () command for meaning of arguments. Note The target_link_libraries () command should be preferred whenever possible.

project (MyProgramExecBlaBla) #not sure whether this should be the same name of the executable, but I always see that "convention" ...

Specify libraries or flags to use when linking a given target and/or its dependents. Usage requirements from linked library targets will be propagated.

Since static libraries do not link to the libraries on which they depend, it is important for CMake to keep track of the libraries so they can be specified on the link line of the executable being created. You could try to use an absolute path in your CMakeLists2:

当我们在写CMakeLists.txt文件时，常常会搞不明白link_directories, LINK_LIBRARIES, target_link_libraries这3者的区别，下面就其详细介绍：. 它相当于g++选项中的-I参数的作用，也相当于环境变量中增加路径到CPLUS_INCLUDE_PATH变量的作用（这里特指c++。. c和 Java 中用法类似）。.

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. /usr/lib/libfoo.so becomes -lfoo ). The full path to the target's artifact will be quoted/escaped for the shell automatically.

LINK_LIBRARIES — CMake 3.22.2 Documentation LINK_LIBRARIES ¶ List of direct link dependencies. This property specifies the list of libraries or targets which will be used for linking. In addition to accepting values from the target_link_libraries () command, values may be set directly on any target using the set_property () command.

My recommendation is to start simple, and then complicate your project further. Let me try to explain how linking works in CMake.

Oct 25, 2021 · Linking CMake Libraries To Other C++ Targets Now that you can create library targets with CMake, the next reasonable step is to use them in your programs! Linking library targets to other targets — whether it’s an executable or another library target — is easy with CMake.

Using the target_link_libraries() statement to control the linked libraries · Open the CMakeLists.txt file and locate the target_link_libraries() ...

add_subdirectory makes the library test defined in libtestproject available to the build. In target_link_libraries we tell CMake to link it to our executable.

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 (). See the target_link_libraries () command for meaning of arguments. Note The target_link_libraries () command should be preferred whenever possible.

21.03.2022 · Short answer: tell CMake that there is dependency between its targets. target_link_libraries (my_program PRIVATE SOMELIB SOMELIBmain) CMake will evaluate SOMELIBs locations for you and link my_program against SOMELIB and SOMELIBmain [1]. Works for both Debug and Release configurations and also for Linux.

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. /usr/lib/libfoo.so becomes -lfoo ). The full path to the target's artifact will be quoted/escaped for the shell automatically.

The idea is that you build modules in CMake, and link them together. Let's ignore header files for now, as they can be all included in your source files. Say you have file1.cpp, file2.cpp, main.cpp. You add them to your project with: ADD_LIBRARY (LibsModule file1.cpp file2.cpp ) Now you added them to a module called LibsModule. Keep that in mind.
