Hi,

When trying CMake tutorial, Code for Step 4 needs update. Please refer to here for possible update [CMake tutorial Step 4 install example is not working as expected - Stack Overflow](https://stackoverflow.com/questions/73623915/cmake-tutorial-step-4-install-example-is-not-working-as-expected)

Thanks

See vre’s answer on SO:

> Your cmake is too old for the `--install` command syntax. `--install` was added to CMake in version 3.15 so you need to install a newer version

Thats right. I resolved the issue. What I’m saying is tutorial code for Step 4 needs to be updated.

This line:

cmake\_minimum\_required(VERSION 3.10)

needs to be changed to:

cmake\_minimum\_required(VERSION 3.15)

?

Thanks for the great tool

Well, the code in the `CMakeLists.txt` file itself works fine with 3.10. It is only the command-line interface described in the tutorial that requires 3.15+. The tutorial step 4 text already says:

> Then run the install step by using the `install` option of the [`cmake`](https://cmake.org/cmake/help/latest/manual/cmake.1.html#manual:cmake(1)) command ( **introduced in 3.15, older versions of CMake must use `make install`** ) from the command line.
