I am trying to use ALE to check definitions and references in vim, but I am unable to do so.
Using the ccls linter and in the output of :ALEInfoit prints :
(Errors for ccls)
Failed to find project root, language server won't start.
Failed to find project root, language server won't start.
The complete output of :ALEInfo is below :
Current Filetype: c
Available Linters: ['cc', 'ccls', 'clangd', 'clangtidy', 'cppcheck', 'cpplint', 'cquery', 'cspell', 'flawfinder']
Linter Aliases:
'cc' -> ['gcc', 'clang']
Enabled Linters: ['cc', 'ccls', 'clangtidy']

Suggested Fixers:
'astyle' - Fix C/C++ with astyle.
'clang-format' - Fix C, C++, C#, CUDA, Java, JavaScript, JSON, ObjectiveC and Protobuf files with clang-format.
'clangtidy' - Fix C/C++ and ObjectiveC files with clang-tidy.
'remove_trailing_lines' - Remove all blank lines at the end of a file.
'trim_whitespace' - Remove all trailing whitespace characters at the end of every line.

I want to avoid using an IDE which comes with features like GoToDefinition and FindReferences. Also learning how to LSPs may be helpful when working with other programming languages as well.
I could use some help now so posting the question here
I have installed ccls using the command sudo apt install ccls. I believe ALE comes with ccls so this shouldn't be necessary.
Searched online for what exactly a project root means in C but found very ambiguous definitions or several definitions
