4.1.1 Special Pragmas

If Cython code is either attached or loaded as a .spyx file or loaded from the notebook as a %cython block, the follow pragmas are available:

clang: may be either c or c++ indicating whether a C or C++ compiler should be used
clib: additional libraries to be linked in, the space separated list is split and passed to distutils.
cinclude: additional directories to search for header files. The space separated list is split and passed to distutils.

For example:

#clang C++
#clib givaro
#cinclude /usr/local/include/
