List of preprocessor include file search directories.
This property specifies the list of directories given so far to the
target_include_directories() command. In addition to accepting

INCLUDE_DIRECTORIES directory property. Both directory and
target property values are adjusted by calls to the
The value of this property is used by the generators to set the include paths for the compiler.
Relative paths should not be added to this property directly. Use one of the commands above instead to handle relative paths.
INCLUDE_DIRECTORIES may use “generator expressions” with
$<...>. See the
manual for available expressions. See the
manual for more on defining buildsystem properties.
