Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Select Debug, Release, MinSizeRel, or RelWithDebInfo and specify it as follows."

A block of code is set as follows:

cmake_minimum_required(VERSION 3.20)
project(Hello)
add_executable(Hello hello.cpp)

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

cmake_minimum_required(VERSION 3.20)
project(app)
message("Top level CMakeLists.txt")
add_subdirectory(api)

Any command-line input or output is written as follows:

cmake --build <dir> --parallel [<number-of-jobs>]
cmake --build <dir> -j [<number-of-jobs>]

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "If all else fails and we need to use the big guns there is always trace mode."
