## Allow to configure the Debugger settings of visual studio
## Note: Using this command under linux doesn't affect anything
## On run Debug Windows local : visual will try to load a specific COMMAND with ARGS in the provided WORKING_DIR
##
## usage:
## MSVCsetUserCommand(	<targetName>
##    [COMMAND 			<myCustomAppToLaunch> | [ PATH <myCustomDirWhereIsDefaultTargetFileNameToLaunch> [FILE <myCustomExecFileToLaunch>] ] ]
##    ARGS 				<associatedArguments>
##    WORKING_DIR		<whereStartTheProgram>
## )
##
## Warning 1 : All arugments () must be passed under quotes
## Warning 2 : WORKING_DIR path arg have to finish with remain slah '/'
## Warning 3 : use COMMAND for external app OR PATH (optionaly with FILE) option(s) to set your built/installed/moved target
##
## Example 1:
## include(MSVCsetUserCommand)
## MSVCsetUserCommand(	UnityRenderingPlugin
## 	  COMMAND 			"C:/Program Files (x86)/Unity/Editor/Unity.exe"
## 	  ARGS				"-force-opengl -projectPath \"${CMAKE_HOME_DIRECTORY}/UnityPlugins/RenderingPluginExample/UnityProject\""
## 	  WORKING_DIR		"${CMAKE_HOME_DIRECTORY}/UnityPlugins/RenderingPluginExample/UnityProject"
## 	  VERBOSE
## )
##
## Example 2:
## include(MSVCsetUserCommand)
## MSVCsetUserCommand(	ibrApp
## 	  PATH 				"C:/Program Files (x86)/workspace/IBR/install"
##	  FILE				"ibrApp${CMAKE_EXECUTABLE_SUFFIX}" ## this option line is optional since the target name didn't change between build and install step
## 	  ARGS				"-path \"${CMAKE_HOME_DIRECTORY}/dataset\""
## 	  WORKING_DIR		"${CMAKE_HOME_DIRECTORY}"
## 	  VERBOSE
## )
