the SFML root directory), but it will then be polluted with a lot of garbage: a complete hierarchy of build files, object files, etc. You can generate them directly in the source tree (ie. The first thing to choose is where the projects/makefiles and object files (files resulting from the compilation process) will be created.

Plus a few other options so that you can create the perfect build that suits your needs - we'll see that in detail later.
#Beginner cmake tutorial how to
Basically it consists of choosing what to build, how to build it and where. If you are a ROS beginner and want to learn ROS basics fast, we recommend you take any of the following courses on Robot Ignite Academy:ĭid you like this video? Whatever the case, please leave a comment in the comments section below, so we can interact and learn from each other.This step consists of creating the projects/makefiles that will finally compile SFML. Prefer “sights and sounds” to “black and white”? We have a video covering this same post, just for you! The configuration directives in CMakeLists.txt must follow a particular order this is why commenting out the ‘project’ directive didn’t work, as the error message also hinted. The order in the configuration DOES count. Your CMakeLists.txt file MUST follow this format otherwise your packages will not build correctly. But what about commenting out parts of the file? Also according to ROS Wiki: Well, now you can see why renaming the file isn’t a good idea.
#Beginner cmake tutorial install
Any CMake-compliant package contains one or more CMakeLists.txt file that describe how to build the code and where to install it to.

The file CMakeLists.txt is the input to the CMake build system for building software packages. Step 3: Master the concept – what is CMakeLists.txt? Let’s talk more about that in the next section. Moral lesson: CMakeLists.txt can make or mar a project, if not properly modified. # Running command: "make -j2 -l2" in "/home/user/catkin_ws/build" Build files have been written to: /home/user/catkin_ws/build # add_compile_options(-std=c++11) user:~/catkin_ws$ catkin_make Project(cmakelists_test) -> uncomment this line We aren’t getting away with tampering with CMakeLists.txt, are we? Now, let’s repent and restore the file: remove the comment from the ‘project’ directive, save and run catkin_make again. Invoking "make cmake_check_build_system" failed
