Hi @SpandanaBaji

Fastest solution is to set CMake flag that depend on libcurl to false, downside is you will not have on-line update suggestions.

example:
cmake ../ -DCHECK_FOR_UPDATES=OFF

If you do need it on please send a full log of the CMake configure + make flow.
We build it in several environments and no regression currently so this is a special case.

Hi Nir-Az,

Accoeding to the log you havn't disables check for updates.
Please share your cmake configure command.
You should do
cmake ../ -DCHECK_FOR_UPDATES=OFF

This is the output, please share the command you are using to trigger that output.

I am not using any command just using project => configure cache in visual studio and I am new to visual studio and cmake things so just using triggering at UI level
