Hi guys,

I'm building ROS melodic from source to an install space inside a docker container. Everything is fine and I copy the workspace from the install space out of the container.

I then try and build the Geometry2 package in a container. I pull the artifacts from the melodic workspace install space into the container and source the setup.bash at /opt/roscustom/setup.bash. The ROS melodic workspace is relocated from its install space /opt/roscustom/install to /opt/ros_custom.

However I get 2 issues. First issue:

CMake Error at /opt/roscustom/share/tf2kdl/cmake/tf2kdlConfig.cmake:113 (message): Project 'tf2kdl' specifies '/opt/roscustom/install/include' as an include dir, which is not found. It does neither exist as an absolute directory nor in '${{prefix}}//opt/roscustom/install/include'.

I think this issue is to do with catkin putting hard-coded paths into the .cmake file for packages that include plain cmake packages. orocoskdl in this example for tf2kdl.

At an attempt to continue with the build I create the /opt/ros_custom/install/include directory inside the container and the build continues with the next error.

[ 46%] Building CXX object third-party-src/testtf2/CMakeFiles/testbufferserver.dir/test/testbufferserver.cpp.o make[3]: *** No rule to make target '/opt/roscustom/install/lib/liborocos-kdl.so.1.4.0', needed by '/opt/roscustom/devel/lib/testtf2/testbufferserver'. Stop.

Again the build is looking for the library that is now in /opt/roscustom/lib/ not /opt/roscustom/install/lib. This isn't an issue for any other catkin package but is for orocoskdl. I applied this PR from the orocoskdl repo to see if it would help https://github.com/orocos/orocos_kinematics_dynamics/pull/255/files/b2cf2070b95e4d842d37dd13922ae3e99ea50381 however it doesn't.

Does orocos_kdl require the ROS workspace installation space remains?

Thanks for your help!
