# - MACRO_OPTIONAL_ADD_SUBDIRECTORY() combines add_subdirectory() with an option()
|
||
|
|
# MACRO_OPTIONAL_ADD_SUBDIRECTORY( <dir> )
|
||
|
|
# If you use MACRO_OPTIONAL_ADD_SUBDIRECTORY() instead of add_subdirectory(),
|
||
|
|
# this will have two effects
|
||
|
|
# 1 - CMake will not complain if the directory doesn't exist
|
||
|
|
# This makes sense if you want to distribute just one of the subdirs
|
||
|
|
# in a source package, e.g. just one of the subdirs in kdeextragear.
|
||
|
|
# 2 - If the directory exists, it will offer an option to skip the
|
||
|
|
# subdirectory.
|
||
|
|
# This is useful if you want to compile only a subset of all
|
||
|
|
# directories.
