FindBoost: Restore finding without CXX language enabled (!2663) · Merge requests · CMake / CMake

Brad King requested to merge brad.king/cmake:FindBoost-no-cxx into master Nov 26, 2018

Since !2579 (merged) we run the internal _Boost_COMPILER_DUMPVERSION macro on all UNIX platforms. Teach the macro to tolerate missing CMAKE_CXX_COMPILER_VERSION, which occurs when the CXX language is not enabled.

Fixes: #18624 (closed)
