Subject: [PATCH] Use boost library names instead of Boost_LIBRARIES var for
 .pc file generation

In recent versions of FindBoost.cmake (e.g. on Ubuntu 20.04),
Boost_LIBRARIES contains the cmake targets (Boost::thread,
Boost::system) instead of library names.

pkg-config --libs class_loader retruns
[...]-lclass_loader Boost::thread\;Boost::system\;[...]

Those cannot be linked downstream when cmake is not used or
find_package(Boost) is not executed again to actually find/define the
targets.
