次の2つに違いはありますか?
set(FOO true CACHE BOOL "description")
option(FOO "description" ON)
背景: しばらく CMake を使用していたとしても、option
今日コマンドに気づいただけなので、常に使用してきset
ました。
In your example, there is no difference. But there can be differences:
Option
has a default value of OFF
.CMakeDependentOption
Set
accepts types other than BOOL
, especially ;-lists.Additionally, when you use an option you are indicating to your user that it can be set safely. Setting internal variables from the outside might subtly break the script with invalid values.
