I was finally able to compile CGAL with gcc 7. I had to disable the following
test in CGAL_SetupBoost.cmake:

* try_run( CGAL_test_cpp_version_RUN_RES CGAL_test_cpp_version_COMPILE_RES
"${CMAKE_BINARY_DIR}"

"${CGAL_INSTALLATION_PACKAGE_DIR}/config/support/CGAL_test_cpp_version.cpp"
RUN_OUTPUT_VARIABLE CGAL_cplusplus)*


The test was apparently failing while compiling with gcc 7, causing
CGAL_requires_Boost_libs to be set to FALSE and preventing linking with the
boost libraries. I should have noticed the smoking gun in the earlier cmake
traces, with the boost libraries that were left unset.
