Adds options to the compilation of source files.
Adds options to the compiler command line for targets in the current directory and below that are added after this command is invoked. See documentation of the :prop_dir:directory <COMPILE_OPTIONS> and :prop_tgt:target <COMPILE_OPTIONS>
This command can be used to add any options, but alternative commands exist to add preprocessor definitions (target_compile_definitions and add_definitions) or include directories (target_include_directories and include_directories).
add_compile_options may use "generator expressions" with the syntax
$<...>. See the cmake-generator-expressions(7) manual for available expressions. See the cmake-buildsystem(7) manual for more on defining buildsystem properties.
