[Ipopt] Trouble building MATLAB interface for Ipopt 3.10.2 on OS/X 10.7.4

[Stefan Vigerske]

Hi,

did you do a make install for Ipopt before trying to build the Matlab 
interface?
Did it install a file ipopt.pc in
/Users/bss/Tools/ipopt/Ipopt-3.10.2/build.matlab/lib/pkgconfig ?

If you only have
/Users/bss/Tools/ipopt/Ipopt-3.10.2/build.matlab/lib64/pkgconfig,
try to copy lib64 to lib.
