If I add this path to TARGET_LINK_LIBRARIES, cmake generates -l/-L
options, but that does not work:

/usr/bin/gcc  -fPIC   -O3 -DNDEBUG -Wl,-E  -L/usr/local/lib
/usr/lib/perl/5.8/auto/DynaLoader/DynaLoader.a
-L/usr/lib/perl/5.8/CORE -lperl -ldl -lm -lpthread -lc -lcrypt -shared
-Wl,-soname,libwzd_perl.so -o libwzd_perl.so
"CMakeFiles/wzd_perl.dir/libwzd_perl.o"
-L/home/pollux/WORK/PROGS/wzd/WZDFTPD/wzdftpd-cmake/build/libwzd-core
-L/usr/lib/perl/5.8/auto/DynaLoader -lwzd_core -lDynaLoader -lperl
^^^^                                             ^^^

-lpthread -lssl
-Wl,-rpath,/home/pollux/WORK/PROGS/wzd/WZDFTPD/wzdftpd-cmake/build/libwzd-core:/usr/lib/perl/5.8/auto/DynaLoader
/usr/bin/ld: cannot find -lDynaLoader
collect2: ld returned 1 exit status

Thanks,
