Conventions used

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

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system.”

A block of code is set as follows:

project( 
"chapter1" 
VERSION 1.0 
DESCRIPTION "A simple C++ project to demonstrate basic CMake usage" 
LANGUAGES CXX 
)

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

include(GenerateExportHeader) 
generate_export_header(hello 
EXPORT_FILE_NAME export/hello/ 
export_hello.hpp)
target_include_directories(hello PUBLIC "${CMAKE_CURRENT_BINARY_DIR} 
/export")

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

cmake -G "Unix Makefiles" -DCMAKE_CXX_COMPILER=/usr/bin/g++-12 -S . 
-B ./build 

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "Although CMake is quite well integrated into many IDEs and editors, it is essentially a command-line tool, so learning how to use CMake in the command-line interface (CLI) is essential to use it to its full potential".
