it seems that the mind version of cmake is 3.19.4 to support finding out of the box - is that correct? No, pretty much any CMake version works. Especially with the CMAKE_PREFIX_PATH approach. If it doesn't you misconfigured something
you're right using the CMAKE_PREFIX_PATH approach using environment or directly with list(APPEND CMAKE_PREFIX_PATH ${HAAS_THIRD_PARTY_LIBS}/boost_1_76_0) also works with 3.18.6 - but NOT using set( BOOST_ROOT ${MY_THIRD_PARTY_LIBS}/boost_1_76_0 ) - that works only with 3.19.4 the CMake guys forgot(or maybe thought i already tried that) to point me to CMAKE_PREFIX_PATH solution - what would have solved my problem instantly and also said that my problem would be solved with 3.19.4) so i tried to "fix" something unbroken based on a maybe not exact enough issue description - my fault thank you soo much
