Building the Xvnc server requires libtool control files of rdr, rfb,

network and Xregion, which a cmake build will NOT produce, this macro 
tries to create a libtool control file *.la for the specified target 
with libdependencies for a static library target.

Due to the automake part of Xvnc references to libtool files in source
tree you need to build vncviewer using cmake in the source tree.
