Hi all,
I encountered a weird build issue when I use PACKAGES_PATH for the package outside WORKSPACE.
Currently I have RedfishClientPkg in the different repo and I configure PACKAGES_PATH as below,
Set PACKAGES_PATH=d:\edk2; d:\edk2-redfish-client

I always get the build error as below,
;-------------------------------------------------------------------------

build.py...
: error 7000: Failed to execute command
        E:\Program Files (x86)\Microsoft Visual Studio 14.0\Vc\bin\nmake.exe /no
logo tbuild [d:\edk2\Build\EmulatorX64\DEBUG_VS2015x86\X64\edk2-redfish-client\R
edfishClientPkg\RedfishFeatureCoreDxe\RedfishFeatureCoreDxe]


build.py...

]


build.py...
: error F002: Failed to build module
        d:\edk2-redfish-client\RedfishClientPkg\RedfishFeatureCoreDxe\RedfishFea
tureCoreDxe.inf [X64, VS2015x86, DEBUG]

;-------------------------------------------------------------------------


However, the build error is gone if I change the naming of external directory to any that doesn't contain "edk2" pattern in the folder name, such as "xxxx" or "edkii-redfish-client".
Is this a known issue? Anyone has the similar experience?

Thanks
Abner
