[CMake] using cmake to link header files: file could be found, is included, but build error when using nmake.

Wed Mar 30 11:15:21 EDT 2016

Dear users at Cmake

It could be that I don't have understood the linking process when building
the project by cmake. The project has three dependencies: (1) Boost, (2)
(Apache) Avro and (3) Botan.
After issuing the following command to be able to use the nmake command
from Visual Studio:

D:\...\build>cmake -G "NMake Makefiles" -DKAA_INSTALL_PATH="D:\kaa\kaaSDK"
> -DKAA_DEBUG_ENABLED=1 ..
>

It ran without problems, except minor warnings like

WARNING: Target "kaacpp" requests linking to directory
> "D:/kaa/kaaBuild/avro_1.8.0/lang/c++/build.win".  Targets may link only to
> libraries.  CMake is dropping the item.
>
=> note: full log is at the bottom of this mail (appendix 1).

but when i call nmake after, it immediately throws up error:

D:\...\build>nmake

I have checked the file, and there is the following includes

#include <sstream>
> #include "boost/any.hpp"
> #include "avro/Specific.hh" <-------- error line
> #include "avro/Encoder.hh"
> #include "avro/Decoder.hh"
>

My idea is that the linking of the avro library is not set up correctly
since the error got thrown after including a Boost file.
Here is a fragment of my cmakelists.txt file where Avro got added and how
the packages got found/added

#  AVRO_ROOT_DIR           - Set this variable to the root installation of
> Avro C++ if the module has problems finding the proper installation path.
> #  AVRO_LIBRARY            - The Avro C++ libraries
> #  AVRO_INCLUDE_DIR        - The location of Avro C++ headers

After that, i have issued the following messaging

message("--- AVRO: Found? " ${AVRO_FOUND}) <----- displays "--- AVRO:
> Found? TRUE"
> message(${AVRO_LIBRARIES}) <----- displays "
> D:/kaa/kaaBuild/avro_1.8.0/lang/c++/build.win"

So, the library can be found. However, it surprises me that the specific
file, Specific.hh could not be found while it is in the include directory,
AVRO_INCLUDE_DIR (according to the findavrocpp.cmake
<https://github.com/Produban/log2kafka/blob/master/cmake/FindAvroCPP.cmake#L33>
it's used for headers).
I have issued the following PowerShell command to show that the file is in
the given directory

PS D:\kaa\kaaBuild\avro_1.8.0\lang\c++\avro> Get-childitem Specific.hh
>
>     Directory: D:\kaa\kaaBuild\avro_1.8.0\lang\c++\avro
>
> Mode                LastWriteTime         Length Name

> -a----         2/9/2012   7:11 PM           7428 Specific.hh
>

So it could be that it is not linking correctly. Is the cmakelist.txt
incorrect or is cmake unable to link the right header file without throwing
an error ?
Is there a solution for this ? I don't have a clue where to find the cause
of the linking problems so i can solve it.

If you need more information, please check the appendix 1 & 2 here below.
If these isn't sufficient enough, please inform me which information i can
provide.

Sincerely
