Is this a library that has built successfully before with another build
system? Has this application been built successfully before?
For instances where the actual implementation is in the .h file, you usually
must make sure you #include that header file in a cpp in your own
application (the app linking against libraryname). .h files are not
compiled on their own: when included in other cpp files, however, their
contents are compiled and available to that object file. My hunch is you
aren't #include-ing the .h files that contain these implementations.
