Can't find compiled mxo files

[GeckoGB]

Hi,

I would like to compile only jit.gl.syphonserver.mxo, using XCode 9.2 on MacOS 10.12.6. But despite "Build succedeed" message, there's no file "Jitter/Server/jit.gl.syphonserver/DerivedData/jit.gl.syphonserver/Build/Products/Debug/jit.gl.syphonserver.mxo"

find DerivedData/Jitter/Build/Products/Debug/

DerivedData/Jitter/Build/Products/Debug/ DerivedData/Jitter/Build/Products/Debug//Syphon.framework DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Headers DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Resources DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Syphon DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A/Headers DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A/Headers/Syphon.h DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A/Headers/SyphonClient.h DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A/Headers/SyphonImage.h DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A/Headers/SyphonServer.h DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A/Headers/SyphonServerDirectory.h DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A/Resources DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A/Resources/English.lproj DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A/Resources/English.lproj/InfoPlist.strings DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A/Resources/Info.plist DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/A/Syphon DerivedData/Jitter/Build/Products/Debug//Syphon.framework/Versions/Current

How can i have the mxo files compiled?

Thanks.
