Using both ADD_PROJECT_DEPEDENCY & FIND_PACKAGE for Boost breaks uses of
${Boost_LIBRARIES}: only the last call to one ore the other is taken
into account.

I suggest to use ${Boost_LIBRARIES} for exported ones, and eg.
${Boost_UNIT_TEST_FRAMEWORK_LIBRARY} for the private ones.

Release of version 4.2.2.

[Tests] fix compilation warnings

Add a comment

Resolve the unused-but-set-variable warning from res value to have a stable release in ros buildfarm

Uncomment this line to resolve the unused-but-set-variable warning to have a stable release in ros buildfarm

Add operations to the unused variables to silence the unused variable warnings in order to have a stable release of dynamic-graph into the ros buildfarm

[cmake] Remove test.cmake

Necessary on clang.

Update package.xml

Remove jrl-cmakemodules because it is called two times and because of that the release in the ros buildfarm did not work.

Add dependencies to build in the ROS buildfarm
