Hello,
I’m experiencing an odd problem where no matter how I set CMP0093, it seems to
use the ‘NEW’ behaviour, breaking some other code relying on the OLD behaviour.
This is Cmake 3.15.4 from Homebrew, other people do report on other platforms
do report the policy working for them. Here’s my code to set the policy, in the
same place we set other policy options:
if(POLICY CMP0093)
message(STATUS "Using old Boost version policy")
cmake_policy(SET CMP0093 OLD)
endif()
The message is printed correctly, but after running find_package(Boost…), the
value of Boost_VERSION is the new dotted syntax (eg 1.71.0) rather than the
old, compatible syntax I need.
Is there anything special about this policy where I might have screwed this up?
I can’t really imagine it’s a Homebrew packaging issue, but also don’t
understand what else I could have gotten wrong syntactically.
Kind regards,
James
