Comment (by HuanEva):

 I have armadillo and armadillo_bits in "/usr/include",   I copied both of
 them to /opt/local/include, but I still got the same error.


 Where could I possible get config.h for clang? I tried some directory, but
 did not find it.


 Is there a way that I can configure XCode such that clang will search
 /usr/include by default.

 /usr/include/ as an include directory, and CMake doesn't do that because
 every sane compiler already does it implicitly.

 > Also, you could try moving your Armadillo headers to
 /opt/local/include/, and I think that would work.  The problem appears to
 be specifically related to the fact that XCode on OS X Mavericks does not
 configure clang to search /usr/include/ by default, but CMake assumes that
 it does and does not add -I/usr/include/ as a result.
