CMake Bootstrap

README.md

Read Me

Building a newer version of CMake yourself is pretty simple, especially with bootstrapping (using an older version of CMake to build the never version).

1. Place this CMakeLists.txt file in a dedicated CMake folder.
2. In this folder, create a build folder and from within it run cmake .. && cmake --build .
3. Your new version of CMake will be installed into install, so you can add install/bin to your PATH
4. To upgrade again, delete the install folder and in the build folder run cmake --build . again
5. When install/bin is in your PATH, check the version of CMake with cmake --version
6. Use your upgraded CMake to modernize your existing CMake projects and build other people's projects that require it
7. Share this script to make other people's lives easier - nobody likes using outdated software
