In my case, when I got this error, the project's structure was:

project
|
|-CMakeLists.txt
|-main.cpp
|-proto
  |
  |
  |--CMakeLists.txt
  |--message.proto

To solve it, I had add to add the "proto" module in the main project's CMakeLists.txt:

add_subdirectory(proto)

Also, you need to add in both CMake's these lines:

find_package(Protobuf REQUIRED)
include_directories(${protobuf_INCLUDE_DIR})

Also, try to look for a variable named something like protobuf_INCLUDE_DIR; there are no guarantees for it's name (Protobuf_*** or protobuf_***).
