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.

Is CMake only for C++?

Starting with just C/C++ project support, modern CMake now supports languages like Fortran, C# and CUDA. Over the years a lot of open source projects migrated from Makefile based build system to CMake.

Is CMake better than make?

CMake is much more high-level. It’s tailored to compile C++, for which you write much less build code, but can be also used for general purpose build. make has some built-in C/C++ rules as well, but they are useless at best.

How do I add multiple files to CMake?

Multiple directories, multiple source files. In this case, you need to write cmakelists in the project root directory demo3 and math directory respectively Txt file. For convenience, we can compile the files in the math directory into a static library, and then call the main function.

Building with Qt Creator
In Qt Creator, go to File → Open File or Project… and choose CMakeLists. txt from the source folder you want to build. Qt Creator will prompt you for the location of the binary folder, calling it the “build directory”. By default, it suggests a path adjacent to the source folder.

Where is CMakeLists TXT located?

CMakeLists. txt is placed at the root of the source tree of any application, library it will work for. If there are multiple modules, and each module can be compiled and built separately, CMakeLists. txt can be inserted into the sub folder.

What is the difference between Include_directories and Target_include_directories?

1, include_directories() is accessible for all the files in the source-tree 2, target_include_directories() is-only accessible for a specific target when compile.

What is Cmake_source_dir?

The path to the top level of the source tree. This is the full path to the top level of the current CMake source tree. For an in-source build, this would be the same as CMAKE_BINARY_DIR .

Is CMake faster than make?

CMake does a two-step build: it generates a low-level build script in ninja or make or many other generators, and then you run it. All the shell script pieces that are normally piled into Makefile are only executed at the generation stage. Thus, CMake build can be orders of magnitude faster.

Makefiles are not obsolete, in the same way that text files are not obsolete. Storing all data in plain text is not always the right way of doing things, but if all you want is a Todo List then a plain text file is fine.

Why use Makefile instead of CMake?

Make (or rather a Makefile) is a buildsystem – it drives the compiler and other build tools to build your code. CMake is a generator of buildsystems. It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions.
