This package makes rather extensive use of the filesystem module introduced around GCC 5.5.x. As the filesystem module was not stabilized until after CXX17, and in GCC 8+, and we are using GCC 7.5.0, there are a number of work arounds that need to be done to get this package compliant with building against 7.5.0. For whatever reason there is an issue of the linker not liking the reference to the file system module. I have set the flags at configure-time, and everything but I am just out of ideas. I hope somebody will have an idea. --8<---------------cut here---------------start------------->8--- ld: CMakeFiles/sys_unit_test.dir/test/PathTest.cc.o: in function
