GF_PLUGIN_FOLDER is not created

[balazsdukai]

On branch: develop

chmod 1777 $geoflow_src && \
    cd $geoflow_src && \
    mkdir -p $GF_PLUGIN_FOLDER && \
    mkdir -p build && cd build && \
    cmake .. \
      -DCMAKE_BUILD_TYPE=Release \
      -DGF_BUILD_GUI=OFF \
      -DGF_PLUGIN_FOLDER=$GF_PLUGIN_FOLDER && \
    cmake --build . --parallel $JOBS --config Release
# Split the install from the build, because it makes easier to debug installation issues
cd $geoflow_src/build && cmake --install .

If the GF_PLUGIN_FOLDER does not exists, it is not created. However, geoflow builds and installs without errors. Only when running it, it complains about the missing GF_PLUGIN_FOLDER.

The same happens even if I don't specify GF_PLUGIN_FOLDER.
It sets GF_PLUGIN_FOLDER to /usr/local/lib/geoflow-plugins (on ubuntu), but does not create the dir.

Could cmake create GF_PLUGIN_FOLDER if it does not exist?
