[Ipopt] Help on compile IPOPT c++ example (covert makefile to CMakeLists.txt), ubuntu 12.04, 64 bit , ipopt 11.0

[Zhenli Lu]

Dear Stefan.
   Thank you very much for your email.
    Now it works with your solution. And I copy the makefile from Ipopt/turtorial/CodingExercise/Cpp/1-skeleton. And change the exe and *.o with my example shown in the documentation, and make, then ./exe it, it works.
   Now I want to know do you know how to change the makefile to a CMakeLists.txt, then I can make it easily to work with the other software in different framework.
   for example, the make file is shown as following, can some one help me to convert it to CMakeLists.txt.

The ftp access to netlib is currently not available.
You can download the ASL archive from
http://netlib.sandia.gov/cgi-bin/netlib/netlibfiles.tar?filename=netlib/ampl/solvers
and extract it in the ThirdParty/ASL directory by hand.

You first have to configure, compile, and install Ipopt (configure;
make; make test; make install). In the examples directories of the Ipopt
build you will then have a usable Makefile.
Makefile.in is just a template that is used by configure to create a
Makefile that fits to your system.
