target_link_libaries(... Boost::boost) seems not to work if the stagedir/<lib> folder is missing but the pre-build binaries missing this folder https://sourceforge.net/projects/boost/files/boost-binaries/1.75.0/ https://sourceforge.net/projects/boost/files/boost-binaries/1.75.0/boost_1_7... boost_1_75_0    <boost>    ...    bootstrap.bat    bootstrap.sh    <lib64-msvc-14.1>      <cmake>      *.lib if i build 1.75.0 from source with b2 --toolset=msvc-14.1 --stagedir=./lib64-msvc-14.1 address-model=64 architecture=x86 link=static threading=multi i've get this hierachy c:\Boost\boost_1_75_0    <boost>    ...    bootstrap.bat    bootstrap.sh    ...    <lib64-msvc-14.1> <-- stagedir      <lib>        <cmake>        *.lib what is the very same hierarchy with Qt6 cmake-configs (so its seems to be "more" standard) C:\Qt\6.1.2   <msvc2017_64> <-- aka "stagedir"     <lib>       <cmake>       Qt6*.lib why does the pre build binary package got a different hierarchy?
