“Why Cmake??” That’s exactly what my question is. Thank you for the information. I understand.

If you want more details how to use CMake, I have a series explaining some of the things you can do.

instead of manually running "ninja" you could have invoked "cmake --build ." While the effect is identical, you don't have to remember which generator was used and what binary name is related to it.

Yeah! I agree that is a great option as well!

I've read that "Make uses Makefiles to make C." "CMake uses CMakeLists to make Makefiles to make Make make C." However, is it possible to use CMake with Visual Studio IDE Community? For example, there are some projects (ex. frang75 / nappgui ) that say the prerequisites are: Visual Studio CMake Kind of ambiguous if this refers to the Visual Studio Code editor or the Visual Studio IDE. BTW, in the latter, there is a drop-down to select if you are want to build a 32-bit or 64-bit exe, how would this be done using CMake?

Having used both VSCode and VS IDE, I'm guessing it is for VSCode. VS IDE is kind of a walled garden experience. It is possible to get CMake to do both 32 but and 64 bit, however it does require knowing which compiler you specifically are using. (As far as I know there isn't a generic way per se.)

I just hit "run code" in visual studio and thats it

Yep, that is an option. However for professional use standard Visual Studio is quite expensive, and it doesn't have releases for Linux and the like.

Why not make?

@sudocpp 4 ай бұрын

Lol, why not just compile manually by command line? There are lots of ways and everyone prefers different ways.

Why cmake instead of make?

@sudocpp 9 ай бұрын

Make works well on Linux, but there isn't a great Make solution for Windows. CMake does allow you to build with Make, ninja, and a few others. Personally I slightly prefer BSDs bmake over GNUs make.

Sorry but the video doesn't answer why cMake at all, it answers more about how to use CMake.

he actually does, it is for cross-platform building. It is so cumbersome to write makefiles, cmake just generates it

Why cmake? You decided that you have nothing better to do with your life? Just write a Makefile and get on with your like. At least make is properly documented.
