List of preprocessor include file search directories.
This property specifies the list of directories given so far to the
This property is used to populate the
INCLUDE_DIRECTORIES target property, which is used by the generators to set the include directories for the compiler.
In addition to accepting values from that command, values may be set directly on any directory using the
set_property() command, and can be set on the current directory using the
set_directory_properties() command. A directory gets its initial value from its parent directory if it has one. The initial value of the
INCLUDE_DIRECTORIES target property comes from the value of this property. Both directory and target property values are adjusted by calls to the
include_directories() command. Calls to
set_directory_properties(), however, will update the directory property value without updating target property values. Therefore direct property updates must be made before calls to
add_library() for targets they are meant to affect.
The target property values are used by the generators to set the include paths for the compiler.
INCLUDE_DIRECTORIES 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.
