Which cmake version do you use there?

The Linux travis builds fail too but with this error:

which means that it needs a special treatment for older OCC versions.

What I am trying to achieve is that I have a sub-directory Geom2d in the part module -- just to avoid to have all source files inside one directory.
Originally I had the CMakeLists.txt file (under Part/App) to control all the source files of the Geom2d sub-directory. This worked well for all the travis and AppVeyor builds and also my local Windows build. However, it failed for my local Linux (Ubuntu 14.04) build because it didn't create the Geom2d directory in the build directory.

I found this https://cmake.org/Wiki/CMake/Tutorials/Object_Library which actually worked well for Windows again and seems to work for OSX, too. Unfortunately, it doesn't work for me either under Ubuntu.

OK, I have restored the old version and have found a way to make sure to create the needed sub-directory. The travis builds have already succeeded again...

Works here too. Thank you.
