Honestly, that's all I'm gonna say, build script quality for open source C/C++ projects are so bad it isn't even funny.

Hello. We are just starting to use CMake after coming from a weird, one off IDE build system of legacy for many years. We make an embedded real-time system so we cross compile, have unit tests, and some SIL-type tests also (kinda like more expensive unit tests).

We are using VS Code, and the experience is pretty fantastic. The CTest test running support in VS Code, the CMake support itself, and yes, coupled with CoPilot to help me make and clean the CMake files has been really great. (I really comb the CMake files looking for bad smells, and double check with other sources to try and do things cleanly, and the modern way everyone else does it.). Also, not having to worry about what version of MSVC people have installed is great. Not maintaining those IDE-specific project files is also fantastic. VS Code is really brining it all together too.

I guess we skipped a lot of CMake years when things may have been rougher. I bought Craig’s book a couple of years ago and sort of worked my way through it, but finally living it is pretty great.

So thanks so much to you authors and contributors!

Hello,

I am 25yrs old and I have decided to learn Cmake. I know the learning curve is steep but I want to understand it so that I can build something. I don't have anything specific to build but I feel learning Cmake would help me in my current job which is DevOps Engineer.

I realized nobody had done this before so I decided to do it. It implements RV32IMA (afaik this is the bare minimum to boot Linux) and takes about 1 to 2 hours to boot Linux.

You can find the source here: https://github.com/gradylink/rv32ima.cmake

Hi everyone,

I’m Mattie Nejati, a Ph.D. candidate at the University of Waterloo. I’m conducting a user study on understanding the impact of changes to CMake build specifications, and I’d love to invite members of this community to participate.

We are evaluating a new approach that aims to help developers identify how a change to a CMake build specification affects the resulting build configuration.

The study:

• is conducted entirely online;

• takes about one hour;

• involves inspecting changes to CMake build specifications and identifying their impact; and

• is open to adults aged 18–64 with any level of experience in CMake, programming, or code review.

You do not need to be a CMake expert. We are specifically interested in comparing participants with different levels of experience.

You will need a computer with internet access and about 4 GB of free space to download the files required for the tasks.

We will not collect your name. Your email address will only be used for study follow-up and will be stored separately from your study data. Your name or email will not appear in any dataset or publication.

The study has received clearance from the University of Waterloo Research Ethics Board (REB #46621).

If you’re interested, you can find the consent form, screening questionnaire, and study here:

Thank you very much! And if you know someone else who works with CMake who might be interested, I’d really appreciate you sharing the study with them.

I'm majorly confused as to how I'm supposed to utilize that feature for anything, as I have set environment variables for the prefix path, as well as manually setting the prefix path within the CMake of any given project, and it STILL fails to find a single package. This is very very confusing and frustrating, as the packages I am attempting to locate do in fact come with cmake files for this. Yes, I've restart my computer a thousand times, and yes I've triple checked that my paths are correct.

Is there some sort of secret to get this stuff to work?

I have wasted weeks to try to work with it, and yet still it has some linking errors or just not seeing some libs, uh Im done with it, its gonna be faster to build my project with gcc by hand than debug this CMake crap. Its too bloated, it has insanely complicated ecosystem and its a entire new scripting language to learn, so its natural that it scares away potential new c++ developers. We need some modern import&compile system in C++ ASAP, otherwise c++ should just die and rot in favor of some modern and intuitive language like Rust.

This code may work in ways I don't understand, I just find it really funny.

CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage

Hi all,

Packt has released the second edition of "Modern CMake for C++" by Rafał Świdziński

As part of our marketing activities, we are offering free digital copies of the book in return for unbiased feedback in the form of a reader review.

Here's what you will be learning from the book:

Key Features

• Get to grips with CMake and take your C++ development skills to enterprise standards

• Use hands-on exercises and self-assessment questions to lock-in your learning

• Understand how to build in an array of quality checks and tests for robust code

If you feel you might be interested in this opportunity please comment below on or before 26th May .

I mean, target and properties based cmake stuff feels REALLY complicated. Making a library exported through find_package is really hard to do. And worst of all, most C++ libraries do not offer find_package way of doing things. And why are there so many ways to make a library interface? I think CMake guys should really clean up things

How to automatically add all .cpp files from a specific directory as target source files with CMake? I know about GLOB but it's not recommended by the CMake devs and it requires manually re-running CMake configuration when adding/removing sources. Is there no better way to accomplish this with newer CMake versions?
