To update or switch versions, run webi cmake@stable (or @v2, @beta, etc).

Files

These are the files / directories that are created and/or modified with this install:

~/.config/envman/PATH.env

~/.local/opt/cmake

Cheat Sheet

CMake is a cross-platform alternative to autoconf that works on Windows, Mac, and Linux

A project structure looks like this:

my-project/
├── build/
├── CMakeLists.txt
├── hello-world*
└── hello-world.cpp

And can be built my running cmake from the build directory:

pushd ./build/
cmake ../
make

How to create a Hello World with CMake

Lets create a hello world program in C++ and build it with CMake.

1. Create a project directory

   mkdir ./my-project/
   pushd ./my-project/
   

2. Create a Hello World C++ file named hello-world.cpp hello-world.cpp:

   #include <iostream>
   
   int main(int argc, char** argv) {
       std::cout << "Hello World!" << std::endl;
       return 0;
   }
   

3. Create a CMakeLists.txt to compile our code CMakeLists.txt:

   project{hello-world}
   cmake_minimum_required(VERSION 3.10)
   
   add_executable(hello-world hello-world.cpp)
   

4. Create a build directory and build the binary

   mkdir ./build/
   pushd ./build/
   cmake ../
   make
   

5. Test the built binary:

   ./hello-world
