Some commands on Windows do not understand forward slash paths and
require backslashes. In order to help projects generate shell
invocations of such commands, provide a generator expression to convert
paths to the shell-preferred path format for the current generator.
This will allow custom commands to generate paths the same way CMake
does for compiler command invocations.
Port code from the KWSys System_Shell APIs into cmOutputConverter.
Drop it from our copy of KWSys because upstream will drop it too,
and by doing it in this commit 'git blame' may have an easier time
connecting the history of the content.
The Convert methods never belonged to the local generator concept, so
split them out now. The cmOutputConverter is cheap to construct and
destroy, so it can be instantiated where needed to perform
conversions. This will allow further decoupling of cmLocalGenerator
from the configure step.
Inherit cmLocalGenerator from cmOutputConverter for the purpose of
source compatibility.
