[CMake] CMAKE_C++_CREATE_SHARED_LIBRARY missing

[Dvir Yitzchaki]

You were close.
I searched for 'C++' in all our CMakeLists.txt and found the line 

set_target_properties(foo PROPERTIES LINKER_LANGUAGE C++)

changed that to CXX and now the error is gone.

Thanks,

Dvir

Rimshot idea:

Quite possibly someone did a
    project(foo C C++)
rather than using the (IIRC - no docs here ATM) correct CXX.
