You have order dependent static libraries which can be solved by constructing a cycle. As Bo stated by constructing the cycle B;A;ImportedExtLib;B;A each library can see each other.
Looking at your original code example it looks like you are importing the libraries as SHARED, but I think these are actually static libraries and should be imported as such so that CMake does the automatic cycle creation. In general CMake doesn't do cycle creation for shared libraries as they are not link order dependent.
