CMake found Boost but not requested libraries - c++

Question

I am trying to add Boost to a C++ application using CMake. I have read through all relevant questions I can find on SO, and I feel I am getting closer to a solution. But the CMake still can't find the requested Boost library for some reasons.
I am trying to find "boost_filesystem". The debug shows CMake is looking for "boost_filesystem-vc141-mt-gd-1_65_1". I do have the file "libboost_filesystem-vc141-mt-gd-1_65_1.lib" in the folder "C:\boost\boost_1_65_1\stage\lib". I suppose this is the file CMake is looking for, but for some reasons CMake says it can't find it.
Here is the procedure I used to build the Boost. This may be too much details for most people but I suspect it may be helpful to another newbie.
download and extract Boost 1.65.1 in folder C:\boost\boost_1_65_1
go to developer prompt command line and run bootstrap.bat under the above folder.
updated file visualc.hpp under C:\boost\boost_1_65_1\boost\config\compiler (see Unknown compiler version while compiling Boost with MSVC 14.0 (VS 2015)!
Replaced the lines in the bottom of the file visualc.hpp :
// last known and checked version is 19.11.25506 (VC++ 2017.3):
#if (_MSC_VER > 1911)
with
// last known and checked version is 19.13.26128 (VC++ 2017.5.6):
#if (_MSC_VER > 1913)
Open another file project-config.jam under the folder boost_1_65_1 and updated the second line to the following:
using msvc : 14.1 : "C:\Program Files (x86)\Microsoft Visual Studio\2017
\Professional\VC\Tools\MSVC\14.13.26128\bin\Hostx64\x64\cl.exe" ;
Go back to developer prompt command line and run the following to build Boost:
b2 toolset=msvc-14.1 address-model=64
It seems I have done the following items correctly:
properly built the libraries, though not using the default directory. I confirmed that the requested library is built.
assigned the path correctly to the CMake designated directories
used CMake find_package() correctly
Here are the relevant versions I am using:
VS: 2017 v15.6.1 with CMake 3.10
Boost version: 1.65.1, built with tool MSVC 14.1
Here is the CMakelist.txt:
cmake_minimum_required(VERSION 3.6 FATAL_ERROR)
project(test)
set(Boost_USE_STATIC_LIBS OFF)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)

set(BOOST_INCLUDEDIR C:\\boost\\boost_1_65_1)
set(BOOST_LIBRARYDIR C:\\boost\\boost_1_65_1\\stage\\lib)
set(Boost_DEBUG 1)
find_package(Boost COMPONENTS filesystem REQUIRED)
message(STATUS "Boost LIBRARIES: " ${Boost_LIBRARIES})
add_executable(test_Boost main.cpp)
target_link_libraries(test_Boost ${Boost_LIBRARIES})
here is part of the output that may be relevant:

Answer 1

libboost_filesystem-vc141-mt-gd-1_65_1.lib is the static version of the filesystem library (the name starts with lib)
In CMake you are searching for the dynamic version:
set(Boost_USE_STATIC_LIBS OFF)
This cannot work. Now you have to options:
switch the OFF to ON
rebuild boost with the following addition:
b2 toolset=msvc-14.1 address-model=64 --build-type=complete
The command --build-type=complete build all supported variants of the libraries. Just to be on the safe side ;-)
