Sebastian Vargas Vargas

Running CMake configure from a Windows Subsystem for Linux using Visual Studio Code Remote doesn't generate the header file with the current source revision, it throws "/home/sebva/SDL/build-scripts/updaterev.sh: 13: cannot create /mnt/c/Users/sebva/.vscode/extensions/ms-vscode-remote.remote-wsl-0.44.4/include/SDL_revision.h.new: Directory nonexistent".
