Cmake add files to target

Importing and Exporting Guide.

Adds a target with the given name that executes the given commands. The target has no output file and is always considered out of date even if the commands try to create a file with the name of the target. By default nothing depends on the custom target. Indicate that this target should be added to the default build target so that it will be run every time the command cannot be called ALL. Specify the files the command is expected to produce but whose modification time may or may not be updated on subsequent builds. If a byproduct name is a relative path it will be interpreted relative to the build tree directory corresponding to the current source directory. See policy CMP for the motivation behind this feature.

Learn to use CMake effectively with practical advice from a CMake co-maintainer. You can also have the author work directly with your team! Updated December Parts of this article have been reworked to account for improvements made with the CMake 3. Key updates are noted within the article. In all but trivial CMake projects, it is common to find targets built from a large number of source files. These files may be distributed across various subdirectories, which may themselves be nested multiple levels deep. With CMake 3. When the number of source files grows large and they get distributed over a number of subdirectories, possibly nested to multiple levels, this quickly becomes unwieldly. It also results in having to repeat the directory structure, which reduces the benefit of structuring source files into directories in the first place. The logical improvement many developers then make is to build up the list of source files in a variable as each subdirectory is pulled in via include. The top level CMakeLists. This allows each subdirectory to define just the sources it provides and to delegate any further nested subdirectories with another include. It also keeps the top level CMakeLists.

Now we can import this executable into another CMake project. The above example shows how easy it is to specify that myLib and any target that links to it also needs to link to the barry library.

In the Project tree, right-click the folder you want to add a file into and select New from the context menu. Choose the desired file type:. Specify the name, type, and additional options for the new file. You can select existing targets or create new targets. Specify the target type, name, and location.

Now you know how to compile a single file using three lines of CMake. But what happens if you have more than one file with dependencies? You need to be able to tell CMake about the structure of your project, and it will help you build it. To do so, you will need targets. Target names must be unique and there is a way to set the executable name to something other than the target name if you really want to. You can make non-built libraries too.

During the previous chapters we learn how to create targets. These targets will build one library or one application. Sometimes it is needed to generate code, copy files or run some commands that are not just compile or link one binary. How can we do that? As the documentation says , this macro "Adds a target with the given name that executes the given commands ".

Quick search. Sources intended to be used via a language's include mechanism. By subscribing you agree to our Terms of Use and Privacy Policy. This Page Show Source. I found that new capability by accident. You also have to list that header as a source of the target before the header will be copied into the framework. The location of each source file is clear and only needs to be considered within the build. For projects that need to support CMake 3. In all but trivial CMake projects, it is common to find targets built from a large number of source files. The CMake targets view offers even more functionality. Hello, Craig! The following points should also be kept in mind: Non-private sources require much more verbose and less convenient syntax, so consider whether the gains from making them non-private are worth it.

Adds a target with the given name that executes the given commands. The target has no output file and is always considered out of date even if the commands try to create a file with the name of the target. By default nothing depends on the custom target.

If you have worked with solutions generated by CMake, this view will look familiar — but unlike a generated solution you will be able to change the underlying CMake project directly in the IDE. Now we can import this executable into another CMake project. It sounds more like you want to work out how to structure your directories such that public headers are in one location and private headers are in a different location. Many thanks — Graeme Reply. Target-dependent expressions are not permitted. Some IDEs have improved over time and now automatically add headers for any associated implementation file, but note that people may stay with older versions of IDEs for quite a few years for various reasons. In this case, we'll create a file called MathFunctionsTargets. The acceptable types include:. The top level CMakeLists. There I just add myLib private directories manually to unit test executable target.
