Source Code Compilation Re: pagmo

[acxz]

Environment

• DART version: 6.8.2
• OS name and version name(or number): Ubuntu 18.04.2
• Compiler name and version number: GCC 7.4.0

Expected Behavior

The expected behavior is for DART to successfully compile with the optional dependency of pagmo.

Current Behavior

When pagmo is not installed, cmake executes fine. (cmake_out_no_pagmo.txt)

After installing pagmo, cmake returns multiple errors. Notice pagmo is found successfully. There seems to be an error with referencing ipopt. (cmake_out_with_pagmo.txt)

Steps to Reproduce

1. Install pagmo via instructions here
   Make sure to enable the PAGMO_WITH_{EIGEN3,NLOPT,IPOPT} cmake options.
   Essentially:

   git clone https://github.com/esa/pagmo2
   cd pagmo2
   git checkout tags/v2.10
   mkdir build
   cd build
   cmake -DPAGMO_WITH_EIGEN3=ON -DPAGMO_WITH_NLOPT=ON -DPAGMO_WITH_IPOPT=ON ..
   sudo make install
   

2. Clone and Build DART

Code to Reproduce

None needed.

Thanks for the report! I could reproduce this error, and it should be fixed by #1301.

Thanks for the fix! Just wanted to pipe in, build is now successful for me.
