- Hard link the
cmake_commands.jsonfile generated after runningcmake -DCMAKE_EXPORT_COMPILE_COMMANDS=1 ..in the build directory.
Set up the dir tree as follows:
___ root | |--- build # artifacts go here |--- src # source files, including main go here |--- include # header files go here |--- libs # library dependencies go here |--- .git # no shit .gitgnore # add build to this

.gitignore contains /build* and .cache
Might have to add libs separately later on. Not sure how to do that.
