// RCRL assumes that the following preprocessor identifiers are defined (easy with CMake):
// - RCRL_PLUGIN_FILE - the full path to the .cpp file used for compilation
// - RCRL_PLUGIN_NAME - the name of the CMake target of the plugin
// - RCRL_BUILD_FOLDER - the root build folder where CMake has generated the build files
// - RCRL_BIN_FOLDER - the folder with compiled binaries - the plugin will be copied/loaded from there
// - RCRL_EXTENSION - the shared object extension - '.dll' for Windows, '.so' for Linux and '.dylib' for macOS
// - RCRL_CONFIG - optional - if the current build system supports multiple configurations at once (Visual Studio, XCode)

// - calls the destructors of persistent variables
// - unloads the plugins and deletes them from the filesystem

// - parses the code for the 3 different sections in single line comments: // global/vars/once

// - parses variable definitions from 'vars' sections - that can lead to parser errors on invalid input
// parsing errors can be obtained through rcrl::get_new_compiler_output()
// - submits the sections for compilation in a non-blocking way using 'tiny-process-library' for the process
// - returns true if the parsing succeeds and the compilation is started
// - can optionally tell if the default mode was actually used (not used when the first thing in
// the code is an explicit section change in a comment) - through the optional boolean pointer
// Shouldn't be called if:
// - compilation is in progress
// - code is empty
