Description
When I use the EXTRA_NAMESPACE option with qt_add_protobuf, my project doesn't build:
qt_add_protobuf(Protos
PROTO_FILES "example.proto"
EXTRA_NAMESPACE "MyNamespace")
The example.proto doesn't define a namespace by itself.
This appears to be an issue during configuration. I get the following CMake error:
CUSTOMBUILD : CMake warning : [C:\QtProtobufBug\cmake-build-vs\Protos_protobuf_registration.vcxproj] No source or binary directory provided. Both will be assumed to be the same as the current working directory, but note that this warning will become a fatal error in future CMake releases. CUSTOMBUILD : CMake error : The source directory "C:/QtProtobufBug/cmake-build-vs" does not appear to contain CMakeLists.txt. [C:\QtProtobufBug\cmake-build-vs\ProtosQt_protobuf_registration.vcxproj] Specify --help for usage, or press the help button on the CMake GUI.
