On opensuse tumbleweed I needed to install the log4cpp-devel package. The FindLog4cpp.cmake file looks for Category.hh and liblog4cpp.so. The log4cpp-devel has the files
/usr/include/log4cpp/Category.hh /usr/lib64/liblog4cpp.so /usr/lib64/pkgconfig/log4cpp.pc Unfortunately it appears that the cmake script doesn't look in /usr/lib64 for the lib, that may be the problem. I'm a little surprised my CMakeCache.txt has HAVE_LOG4CPP=TRUE. Perhaps there's another mechanism to find the libs. Jared.
