Thank you for reporting. Let me reproduce the issue.

@m-mizutani : I threw this together to help you out.

cd test
mkdir build
git init
git submodule add https://github.com/m-mizutani/libfluent.git
git submodule add https://github.com/msgpack/msgpack-c.git
echo "cmake_minimum_required(VERSION 2.6)" > CMakeLists.txt
echo "add_subdirectory(msgpack-c)" >> CMakeLists.txt
echo "add_subdirectory(libfluent)" >> CMakeLists.txt
cd build
cmake ../

Sorry for late reply. I was investigating EXPORT mechanism of cmake because I'm also not an expert of cmake.

I found two way to avoid the error.

1. use -DFLUENT_INSTALL=OFF option that is implemented at b75a8b8 when running cmake command with your CMakeLists.txt. The option makes installation commands including export cmake.config function disable. Then, your cmake command will not fail on install(EXPORT "fluentConfig" ...)
2. use ExternalProject_Add command in your CMakeLIsts.txt. I thought it's a proper way if you allow to install msgpack and libfluent into your development environment. Please see details of ExternalProject_Add from folloing URL.

Let me close the issue, but please feel free to reopen if you have more issue.
