The compilation database acts in a similar way to the compilation database (compile_commands.json) used by clang-tidy, i.e. it provides additional information about the compilation of project files to help the language server. The main piece of information provided by the PDLL compilation database in this commit is the set of include directories used when processing the input .pdll file. This allows for the server to properly process .pdll files that use includes anchored by the include directories set up in the build system. The structure of the textual form of a compilation database is a yaml file containing documents of the following form: ``` --- !FileInfo: filepath: <string> - Absolute file path of the file. includes: <string> - Semi-colon delimited list of include directories. ``` This commit also adds support to cmake for automatically generating a `pdll_compile_commands.yml` file at the top-level of the build directory.
