Hi Wim, Craig is the CMake specialist in our team, so it is always better to send this stuff to the mailinglist as more people can take a look onto this.
Strangely I never had problems when building PoDoFo with libJpeg on Windows
with Visual Studio. Did you add something like "-DCMAKE_INCLUDE_PATH=c:
\progra~1\gnuwin32\include" to the commandline when invoking cmake so that
the include path is added? According to the readme and my experiences this is
neeeded.
regards
Dom
