[boost] boost libs compiled for gcc toolset with boost 1.67 and CMake 3.11 won't find libs

Hi, I discovered that the latest version of boost does not work with CMake when using the GCC toolset. I submitted this bug: https://gitlab.kitware.com/cmake/cmake/issues/17974#note_408614 Using MSVC as the toolset is fine on windows, but using mingw (gcc compiler) cannot find the libs unless I take out ‘x32’ or ‘x64’ from the name after compilation.
