Yes, I reported it, but I cannot either find the message...

Anyhow it is related to the one of the tests in the
ufl-jit-assemble-chain test suit, which uses boost_math. In the
distutils system we always linked to boost_math and the problem was
avoided.

We can fix it by:

1) Add boost_math when configuring ufc and also add it to the
UFCConfig.cmake file.

2) Add boost_math as an additional lib dependency when JIT compiling UFC
modules. This will add back runtime configuration to JII compiling.

3) Expose a number of configuration options like libs, lib_dirs aso to
the cmake build system and let the user provide the whereabout of an
external library.

There are pros and cons with all of these. The last one looks most
attractive to me, but requires the most work. 1 also seams attractive as
the bessel function is exposed in UFL and hence should be available when
generating UFC forms.
