Hi Karel,
I've noticed a few points where you could start looking for a solution:
* You're mentioning that CMake warns about some linking stuff, but the
compiler error is one about including a header file. Libraries and headers
are fundamentally different objects: header files are used by the compiler,
libraries are used by the linker.
* Regarding the linking thing:
AVRO_LIBRARY - The Avro C++ libraries
Yet you seem to be setting this to a directory:
set(AVRO_LIBRARY
D:/kuleuven/thesis/kaa/kaaBuild/avro_1.8.0/lang/c++/build.win)
when you're supposed to set it to a library (.lib file).
* As for the header issue, you're setting:
set(AVRO_INCLUDE_DIR
D:/kuleuven/thesis/kaa/kaaBuild/avro_1.8.0/lang/c++/avro)
but then using:
include_directories (
${AVRO_INCLUDE_DIRS}
)
Note the difference in the trailing 'S'.
* Additionally, variables like AVRO_INCLUDE_DIR and AVRO_LIBRARY look like
something the find package should be setting *for* you. It doesn't seem
like a package shipped with CMake, so consult its docs to check you're
using it as intended.
