[Ipopt] Problem running Ipopt matlab interface

Hi,

it seems to pick up the wrong IpoptConfig.h file.
It should take
/homes/numerik/paul/lib/Ipopt/include/coin/IpoptConfig.h, but it took 
the one from /homes/numerik/paul/lib_src/CoinIpopt/Ipopt/src/Common/.

Can you confirm that /homes/numerik/paul/lib/Ipopt/lib/pkgconfig 
contains an ipopt.pc file where the Cflags are such that they have 
-I/homes/numerik/paul/lib/Ipopt/include/coin in the beginning.
Or the problem are all the paths in your pkg-config path that do not 
belong there.

A workaround could be to change the matlab interface makefile to say only
INCL = -I/homes/numerik/paul/lib/Ipopt/include/coin
