I get this warning

CMake Warning (dev) at C:/Data/Projects/QtBuildTools/utils.cmake:670 (add\_custom\_command):  
+ CategoryInfo : NotSpecified: (CMake Warning (…ustom\_command)::String) , RemoteException  
+ FullyQualifiedErrorId : NativeCommandError  
+ PSComputerName : localhost

The following keywords are not supported when using  
add\_custom\_command(TARGET): DEPENDS.  
NotSpecified: (:String) , RemoteException  
Policy CMP0175 is not set: add\_custom\_command() rejects invalid arguments.  
Run “cmake --help-policy CMP0175” for policy details. Use the cmake\_policy  
command to set the policy and suppress this warning.  
Call Stack (most recent call first):  
C:/Data/Projects/QtBuildTools/build.cmake:371 (UTILSF\_CopyArtefactsToMain)  
CMakeLists.txt:11 (UTILSF\_BuildLibrary)

now according to the docs of 4.0.2 DEPENDS is a valid keyword.

this is the cmake code

```
foreach( a IN LISTS ${_Artefacts} )
	add_custom_command(
		TARGET ${tgt}
		POST_BUILD
		DEPENDS ${OPTS_SOURCEDIR}/${a}
		COMMAND ${CMAKE_COMMAND}
			"-DTO_COPY=${OPTS_SOURCEDIR}/${a}" 
			"-DCOPY_TO=${${_DestDir}}" 
			-P ${QtBuildtoolsDir}/copy_if_exists.cmake
		VERBATIM )
endforeach()

```

add\_custom\_command(TARGET) does not support DEPENDS, only add\_custom\_command(OUTPUT) does.
