In my ~/.vim/vimrc, I have:

set shiftwidth=4 set tabstop=4 

and when I edit a plain text file, that is respected. However, when I edit a CMake file - these both becomes 8. I tried leafing through /usr/share/vim/vim90/syntax/cmake.vim, but couldn't find something which looks like an override of these values.

What's causing this? Is there a definition I've missed? And - can I override it somehow?

• Nothing in /usr/share/vim/vim90/syntax/cmake.vim seems to be related to tab stops, or to include another vim file.
• Same for /usr/share/vim/vim90/syntax/cmake.vim.
• The CMakeLists.txt files I'm editing have no modeline.
