failed to init with cmake 3.16.0

[cvluca]

I have no issue with cmake 3.15.5 on Ubuntu 18.04, but it failed to init when I update to the newest cmake version.

Hi @cvluca , are you able to provide a build log?

Hi @cvluca , are you able to provide a build log?

@kent-mcleod There is no cmake log being generated. This is what the error looks like.

Hmm, It seems the issue is because of this change:

The cmake(1) -C option now evaluates the initial cache script with CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR set to the top-level source and build trees.
https://cmake.org/cmake/help/v3.16/release/3.16.html#other-changes

Currently the setttings.cmakes script uses the old behavior to detect the stage of build configuration. Will likely need to update to a different mechanism.

Yes, same issue I am seeing as well. Is there any update on this till now? How should I proceed further?

[kent-mcleod]

@debankan777, @cvluca I think I have a fix for it now.
