Are you looking to brush up on your CMake skills and prepare for your upcoming 2022 job interview? If so, you’ve come to the right place. In this blog post, we’ll be discussing the top CMake 2022 frequently asked interview questions and how to best prepare for them. CMake is a powerful and cross-platform open-source build system used to generate native build files for various platforms and compilers. With its ability to generate custom build scripts and manage complex compilation environments, it’s become increasingly popular among software developers, making it a necessary skill to have when applying for programming and software engineering positions. In order to help you ace your upcoming CMake interview, we’ve compiled a list of the most common CMake interview questions you may encounter. We’ll also provide some tips and tricks on how to answer them so you can make the best impression possible. So, let’s get started!
TOP 7 Interview Questions & ANSWERS for 2022!
To help you prepare for the most common questions asked during job interviews, Wisdom Jobs Cmake Interview Questions and Answers were created. Here, we’ve provided advice on how to answer Cmake interview questions. These Cmake Interview questions and answers can be helpful for programmers at all levels of experience, from beginners to experienced ones, as well as job seekers. Its a good idea to go through Cmake Interview Questions. All the best in your job search.
This means that there is a CMakeCache. Txt file in the source tree, most likely as part of an already-built in-supply version If a directory with a CMakeCache is given the CMake course Txt file, it assumes the directory is a build tree. Therefore if one runs “cmake . /mysrc” to construct out-of-supply however there may be a mysrc/CMakeCache. Txt file, after which cmake will handle mysrc due to the construct tree This is a aspect-effect of the characteristic that allows “cmake . ” to be used to regenerate a build tree. The behavior won’t change because mixing in-source and out-of-source builds is unsafe in addition (configured headers could be found in the wrong place).
The CMake cache stores CMake construct settings in a manner similar to how a project’s construct tree is saved. They are referred to as “cache entries” by CMake and are unrelated to the environment variables in your command shell. To edit cache entries, use the wizard mode (cmake -i) or the CMake GUI (CMakeSetup on Windows or ccmake on UNIX). When cmake is first run to provide a new construct tree, the -D command line argument can be used to specify initial values for a build.
CMake has a listing statistics kind. A list is stored as a string of list elements with semicolons between them. Arguments to a SET announcement that are separated by whitespace are treated as list elements. For instance, SET(var a b c d e) provides “var” a cost of a; b c d e, and various CMake instructions may use this list. However, passing a;b;c;d;e to a non-CMake external device, such as a compiler’s command line, is not what you want. Instead, you must either pass “$var” to convert the list to a whitespace-separated string or use SET(var “a b c d e”) in the first position to work with a string rather than a list.
CMake does no longer presently aid convenience libraries. An archive of components to be incorporated into other libraries is what GNU libtool refers to as a “convenience” library. GNU libtool never installs the benefit library, and no packages have ever “linked” to the benefit library. Other libraries “link” to the convenience library, but the convenience library no longer exports any symbols. This does not imply that a project utilizing convenience libraries cannot be converted to CMake. Instead, each goal that requires them might index the source files. They will be built separately for each target using all of the flags and preprocessor definitions set up for that target.
The task of writing the input documents for a local build device belongs to a CMake Generator. To determine which local build system will be used for a build tree, exactly one of the CMake Generators must be chosen. To provide task files for an additional IDE, one of the Extra Generators can be chosen as an alternative to a number of the Command-Line Build Tool Generators.

FAQ
Should I use CMake or Makefile?
The real difference is therefore that CMake is much more high-level. Although it’s designed to compile C++, which requires much less build code to do so, it can also be used for general build. Additionally, make has some built-in C/C++ rules, but they are essentially useless.
Is CMake still used?
Despite all the criticism, CMake has actually gained popularity for a good reason, and C++ developers still rely on it as one of their most important tools. To determine if it’s the best tool for your project, you’ll need to dive in and learn more about it (and its history).
Is CMake easy?
Using CMake is simple. One or more CMakeLists are created to control the build process. txt files in each project’s directory (including any subdirectories)
Is CMake the industry standard?
The de facto industry standard for C/C++ multiplatform and even single OS development is this.
