include_directories
|
|
-------------------
|
|
|
|
Add include directories to the build.
|
|
|
|
::
|
|
|
|
include_directories([AFTER|BEFORE] [SYSTEM] dir1 dir2 ...)
|
|
|
|
Add the given directories to those the compiler uses to search for
|
|
include files. Relative paths are interpreted as relative to the
|
|
current source directory.
|
|
|
|
The include directories are added to the directory property
|
|
INCLUDE_DIRECTORIES for the current CMakeLists file. They are also
|
|
added to the target property INCLUDE_DIRECTORIES for each target in
|
|
the current CMakeLists file. The target property values are the ones
|
|
used by the generators.
|
|
|
|
By default the directories are appended onto the current list of
|
|
directories. This default behavior can be changed by setting
|
|
:variable:`CMAKE_INCLUDE_DIRECTORIES_BEFORE` to ON. By using AFTER or BEFORE
|
|
explicitly, you can select between appending and prepending,
|
|
independent of the default.
|
|
|
|
If the SYSTEM option is given, the compiler will be told the
|
|
directories are meant as system include directories on some platforms
|
|
(signalling this setting might achieve effects such as the compiler
|
|
skipping warnings, or these fixed-install system files not being
|
|
considered in dependency calculations - see compiler docs).
