> My project uses thrift as a third-party git submodule, and build it using CMake.  I have a few other third-party submodules, so I added my CMakeLists.txt to build them together, here is my project tree:
> {code:java}
> -myproj
>     -build (where out-of-source build happens)
>     -src
>         -CMakeLists.txt (to build my project sources)
>     -thirdparty
>         -thrift (using branch 0.11.0 as git submodule)
>         -foo (another git submodule)
>         -CMakeLists.txt (to build all third-party components)
> {code}
> To build all third-party components:
> {code:java}
> myproj/build$ cmake ../thirdparty
> sudo make install
> {code}
> From the output of "make install" there is 
> {code:java}
> -- Installing: /usr/local/include/thrift/thrift/config.h
> {code}
> The expected result is "/usr/local/include/thrift/config.h".
> This is because [thrift/lib/cpp/CMakeLists.txt|https://github.com/apache/thrift/blob/0.11.0/lib/cpp/CMakeLists.txt] line 212 uses CMAKE_BINARY_DIR, which your expect is the root binary directory of thrift, but now is changed because I defined a "wrapper" CMakeLists.txt, hence "thrift/thrift/config.h", then compile error occurs. Maybe CMAKE_CURRENT_BINARY_DIR is a better option here?
