Structuring Projects

In this chapter, we will cover the following recipes:

• Code reuse with functions and macros
• Splitting CMake sources into modules
• Writing a function to test and set compiler flags
• Defining a function or macro with named arguments
• Redefining functions and macros
• Deprecating functions, macros, and variables
• Limiting scope with add_subdirectory
• Avoiding global variables using target_sources
• Organizing Fortran projects
