Would you recommend some practical CMake reference for Raspberry Pi Pico?

Perhaps all the miscellaneous software tips blogs people produce could be wrapped up into a small monthly booklet. A bit like Dr Dobbs used to be, but obviously a lot slimmer. It would encourage people to use the tips in unrelated projects too, since, for instance, the tips here also apply to non-Pico projects too. If they were all in a booklet, people could browse through monthly.</p><img src="https://community.element14.com/aggbug?PostID=24828&AppID=86&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/products/raspberry-pi/b/blog/posts/raspberry-pico-and-cmake---create-your-own-c-lib-with-header-filesTue, 22 Nov 2022 00:08:08 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:bcd675de-ca68-4325-8a44-b42d71577bfbshabaz0<p>Very useful! I&#39;m slowly learning CMake project-by-project, and am glad that the Pico SDK based projects use CMake. Also the libraries&nbsp;are&nbsp;handy when saving projects, since you can then split up your project into separate repositories, and use the git clone submodule functionality to pull in the libraries,&nbsp;to simplify reuse in other projects.</p><img src="https://community.element14.com/aggbug?PostID=24828&AppID=86&AppType=Weblog&ContentType=0" width="1" height="1">
