Hello I am trying to build the overlay but getting an error regarding the HLS IP.  
Initially completed running source build\_ip.tcl after this running source base.tcl encountered with the following error:

ERROR: [BD::TCL 103-2012] The following IPs are not found in the IP Catalog:  
[xilinx.com](http://xilinx.com):hls:trace\_cntrl\_64:1.4 [xilinx.com](http://xilinx.com):hls:trace\_cntrl\_32:1.4 [xilinx.com](http://xilinx.com):hls:color\_convert:1.0 [xilinx.com](http://xilinx.com):hls:pixel\_pack:1.0 [xilinx.com](http://xilinx.com):hls:pixel\_unpack:1.0
