Moreover, you may not say $<TARGET_FILE_NAME:libopenrave0.3> but
$<TARGET_FILE_NAME:libopenrave>0.3, supposed there is no actual
target "libopenrave0.3". However, the symlinks to the soname'd
libraries are automatically generated by CMake if the SOVERSION
or VERSION target property is set, so there should be no need to
do it yourself - in contrast to executables where the POST_BUILD
custom command is quite handy if you want to have them versioned,
too.
