[ros2] Cannot specify link libraries for target "tinyxml2_vendor"

[norro]

In my downstream project diagnostic_aggregator, cmake find_package of pluginlib fails since the latest changes with:

...
-- Found tinyxml2_vendor: 0.7.0 ({snip}/install/tinyxml2_vendor/share/tinyxml2_vendor/cmake)
CMake Error at {snip}/install/pluginlib/share/pluginlib/cmake/pluginlib-extras.cmake:49 (target_include_directories):
  Cannot specify include directories for imported target "tinyxml2_vendor".
Call Stack (most recent call first):
  {snip}/install/pluginlib/share/pluginlib/cmake/pluginlibConfig.cmake:41 (include)
  CMakeLists.txt:15 (find_package)


CMake Error at {snip}/install/pluginlib/share/pluginlib/cmake/pluginlib-extras.cmake:51 (target_link_libraries):
  Cannot specify link libraries for target "tinyxml2_vendor" which is not
  built by this project.
Call Stack (most recent call first):
  {snip}/install/pluginlib/share/pluginlib/cmake/pluginlibConfig.cmake:41 (include)
  CMakeLists.txt:15 (find_package)

(I shortened the workspace path)

This may be in some kind of connection with #191?
