warning: catching polymorphic type ‘class std::exception’ by value [-Wcatch-value=]

I have an issue compiling tests with hippomocks. It is just a warning but:
Scanning dependencies of target src_module_tests
[ 33%] Building CXX object tests/ut/CMakeFiles/src_module_tests.dir/tests/src/module_tests.cpp.o
In file included from /home/michal/mutate_tests/test/tests/tests/ut/tests/src/module_tests.cpp:2:

looks not very nice.
I use SID distro with gcc/g++ version 8.2.0
