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: "After setting the project name, this macro uses the GLOB_RECURSE function to collect all source and header files into the SRC_FILES and HEADER_FILES variables."

A block of code is set as follows:

macro(SETUP_GROUPS src_files)
  foreach(FILE ${src_files})
    get_filename_component(PARENT_DIR "${FILE}" PATH)

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

macro(SETUP_APP projname)
  set(PROJ_NAME ${projname})
  project(${PROJ_NAME})

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

sudo apt-get update

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Choose Custom Installation and make sure that the pip box is checked."
