It has, for example, the PATH to the compiler gonna be used, and the release mode, FLAGs, etc.Īnd the Makefile.txt has all the information the local make program needs to know to build the project(specify the build variables, preprocess, how to generate object files, etc.), unlike CMakeCache.txt CMake does not recommend users change Makefile.txt. Which generates the following files in the build folder:ĬMakeCache.txt is more like the configuration file generated when CMake runs for the first time. I am going to generate the Unix Makefiles for one of my ECE4760 Lab examples.īy running the following command in my build dir, CMake will be looking at the upper folder for the CMakeLists.txt. Microsoft Visual Studio uses NMAKE.Īlternatively, it is also possible to call CMake functions to build the generated MakeFiles by calling cmake -build. This will become the name of the resulting Visual Studio solution. As always, this file should start with cmakeminimumrequired and project command that defines the name of the CMake project. First you will need to create a CMakeLists file at the top of your source code directory. On macOS(as it is based on UNIX) make is a tool from GNU which is included in the Xcode developer toolkit( GNU.org). To convert a Visual Studio solution to CMake involves a few steps. Its based on CMake, so you dont have to create or generate Visual Studio projects. Instead of thinking of CMake as a “C/C++ program maker,” I tend to say it as a “Cross-platform maker.” As its design principle says: “CMake is designed to be used in conjunction with the native build environment.”( ) thus, it is independent of the Operating System it is working on(thus, the compilers), Which means as long as we configure the CMakeLists.txt correctly, CMake should “generate standard build files (e.g., makefiles on Unix and projects/workspaces in Windows MSVC).” on all the supported OS( ) Make ⌗ This tutorial shows how to use Visual Studio for C++ cross platform development on Windows and Linux. Well, long story short: Cmake is a cross-platform Makefiles generator, while make “reads the makefile and invokes a compiler, linker, and possibly other programs to make an executable file.( Microsoft) CMake ⌗ When playing with my RP2040, following the official SDK instructions, I wonder why I have to type cmake then do make, why does it take two steps to build my project?
