How do you link libraries in CMakeLists?

Linking libraries to executables with CMake Let’s start by adding the library’s directory as a subdirectory to our myapp project. 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.

How do I link a static library to a shared library CMake?

Either compile using -fPic (necessary on everything but Windows) in order to create position-independent code which will allow linking the static libraries into a single shared library or decompress all static libraries (e.g. using ar ) and re-link them into a shared library (which I think is an inelegant & non- …

What is target link libraries?

Link a target to given libraries. Specify libraries or flags to use when linking a given target. The named must have been created in the current directory by a command such as add_executable() or add_library() .

How does CMake find libraries?

cmake, which is the typical way for finding libraries. First CMake checks all directories in ${CMAKE_MODULE_PATH}, then it looks in its own module directory /share/cmake-x.y/Modules/. If no such file is found, it looks for Config.

What is an interface library CMake?

Interface Libraries add_library(<name> INTERFACE) Creates an Interface Library. An INTERFACE library target does not compile sources and does not produce a library artifact on disk. However, it may have properties set on it and it may be installed and exported.

Where is my CMake executable?

Source files are in Project/src , and I do the out-of-src build in Project/build . After running cmake ../ ; make , I can run the executable thusly: Project/build$ src/Executable – that is, the Executable is created in the build/src directory.

How do I specify a library path in CMake?

Concretely speaking there are two ways:

1. designate the path within the command. find_library(NAMES gtest PATHS path1 path2 pathN)
2. set the variable CMAKE_LIBRARY_PATH. set(CMAKE_LIBRARY_PATH path1 path2) find_library(NAMES gtest)

What does CMake add library do?

It allows the path to an imported library (often found using the find_library() command) to be used without having to know what type of library it is. This is especially useful on Windows where a static library and a DLL’s import library both have the same file extension.

How do I add a library path to CMake?

Where does CMake look for include files?

cmake is searched first in CMAKE_MODULE_PATH , then in the CMake module directory. There is one exception to this: if the file which calls include() is located itself in the CMake builtin module directory, then first the CMake builtin module directory is searched and CMAKE_MODULE_PATH afterwards.
