I am now seeing this failure on other packages too on ubuntu-latest:

Here is a failure with lzo as well as hiredis.

I'm testing a edit to pkg-cmake.mk to add this to default options:

# Some packages requires CMake 3.0.0 but latest CMake requires >=3.5
# Set the policy version minimum to force these packages to 3.5 or greater.
$(2)_CONF_OPTS += -DCMAKE_POLICY_VERSION_MINIMUM=3.5

This would fix it across the board.

Best regards,
