catkin build system problem

After recent PR #3, I've got a problem with compiling nlopt catkin package.

Generally, it seems that the path to the libnlopt_cxx.a is wrong. It resides in ~/catkin_ws/devel/lib directory (it's really there) and the path in ${NLOPT_INSTALL_DIR} points to a non-existent location nlopt_install/home/dymczykm/catkin_ws/install/lib/:

• the prefix nlopt_install is wrong
• there's no install dir in my catkin_ws

The error message from catkin build tools looks as follows:

make[2]: *** No rule to make target `nlopt_install/home/dymczykm/catkin_ws/install/lib/libnlopt_cxx.a', needed by `/home/dymczykm/catkin_ws/devel/lib/libnlopt_wrap.so'

The previous master version a461864 works fine on the same system.

How to use this package?

Hi,
I am trying build my ROS package which contains some optimization code writtten with nlopt library.
But I am not able to compile the package successfully as the catkin build system is not linking the nlopt headers correctly.
I came across this package in search for the solution of my problem but I have no idea how this package is used?
I built the workspace containing this package but no file is generated in the /include directory of this package.
Please help me understand what this package does and how is it used?

nlopt seems to export the wrong include folder

To me it seems that this line

nlopt/CMakeLists.txt

Line 15 in bd13b06

INCLUDE_DIRS include

should export ${CATKIN_DEVEL_PREFIX}/include instead - as for example here https://github.com/ethz-asl/protobuf_catkin/blob/master/CMakeLists.txt#L29.

@eggerk , I believe this to be behind the problem in http://129.132.38.183:8080/job/test_subtree_multiagent_mapping/19/.
