Cannot find CMAKE_ROOT on Windows

Hello, I’m pretty new to PlatformIO, I’m just using it to test a project I’ve found on another repository. So this might be just a misconfiguration on my part, but I can’t find how to fix it in the docs or the IDE.

Anyway, the problem is that the project is failing to build because it can’t find CMAKE_ROOT, meaning that it can’t use cmake to build the project, I’ve looked into the .platformio folder to see if the cmake package was downloaded and it was.

I’m on Windows and cmake is located in the folder packages\tool-cmake\bin inside the .platformio folder, but the build configuration of the project is looking for cmake in the packages\tool-cmake\share\cmake-3.16 folder, which doesn’t exist.

This is the complete output of the build terminal:

Strange, but I cannot reproduce the issue on my Windows machine., the project compiled just fine. Could you please delete the folder C:/Users/MyUser/.platformio/packages/tool-cmake and try to compile your project again?

I know this is a pretty simple fix to an unknown cause, but I think it would be great if it was added somewhere in the docs!

For some reason your previous installation for the CMake packages was corrupted (maybe installation process was interrupted, an antivirus didn’t like the package, etc.). Anyway, you are the first one who reported such a problem for the last several years. I believe we can consider this problem as a one-time incident.
