I've setup lsp-mode and clangd, and put the compile-commands.json in the projects root.
I can tell compile-commands.json because my cflags are included in the Updating file output of *clangd::stderr* log.
However, whenever I run lsp-find-definition it simply prints:lsp-request: method not found
... unless the function happens to be defined in the same file.
How to troubleshoot this? it makes lsp-mode quite useless.
Checking the logs gives no hints as to why it fails to find the method.
For reference this is the output of lsp-describe-session:
