Well, I get the cmake lines you introduced:

====================================================
-- Creating a statically linked executable
-- Disabling dynamic loading of plugins from the input file
-- Autopilot invoked

But still the linker complains about the dlopen and dlerror calls,
although they now should not even be compiled from what I saw in your
commit. I also made a 'make distclean' before testing so there are no
old files around. The error messages are:

Linking CXX executable aspect
CMakeFiles/aspect.dir/source/main.cc.o: In function
`possibly_load_shared_libs(std::string const&)':

Maybe the Precompiler-Variable you set in CmakeLists did not make it to
main.cc? I am not very familiar with cmake, so I do not know how to test
this.

I can certainly post the results as soon as they are finished.
