CMake with Boost 1.62.0: "No Boost libraries were found" - c++

Using the following CMake code:
cmake_minimum_required(VERSION 3.6)
project(TrustLineManager)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(BOOST_ROOT D:/Tools/boost_1_62_0/)
set(Boost_INCLUDE_DIRS D:/Tools/boost_1_62_0/boost)
set(Boost_LIBRARY_DIRS D:/Tools/boost_1_62_0/libs)
set(BOOST_INCLUDEDIR C:/MinGW/include)
set(BOOST_LIBRARYDIR C:/MinGW/lib)
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
find_package(Boost
1.62.0
COMPONENTS system
filesystem
REQUIRED)
include_directories(${Boost_INCLUDE_DIRS})
target_link_libraries(TrustLineManager ${Boost_LIBRARIES})
I get this error:
Error:Unable to find the requested Boost libraries.
Boost version: 1.62.0
Boost include path: D:/Tools/boost_1_62_0
Could not find the following static Boost libraries:
boost_system boost_filesystem
No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT to the location of Boost.
What should I do to solve it?
EDIT:
I modified my CMake code into:
cmake_minimum_required(VERSION 3.6)
project(TrustLineManager)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp)
set(BOOST_ROOT "D:/Tools/boost_1_62_0")
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
find_package(Boost)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(TrustLineManager ${SOURCE_FILES})
target_link_libraries(TrustLineManager Boost::filesystem Boost::thread)
I have now this error:
Error:Target "TrustLineManager" links to target "Boost::filesystem" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing?
Here is a screenshot of Boost directory contents:

Obviously CMake finds Boost as it is able to detect its version (1.62.0).
CMake uses the file FindBoost.cmake to determine what libraries to link against.
This file is updated continuously when new boost versions appear.
There, support for Boost 1.62.0 is available only for CMake >= 3.7.0.
So just update your CMake version (or just the file FindBoost.cmake) and you will be fine.

cmake find_package: why cannot find some components in boost

Find_package command is a nightmare to me.
I am trying to include some specified components in boost into my project.
Some components could not be found with find_package command for different error.
Can anyone help to explain the error reported?
case 1:
cmake_minimum_required(VERSION 3.15)
project(tryBoost)
set(CMAKE_CXX_STANDARD 14)
set(BOOST_ROOT "D:\\cygwin64\\home\\yubo\\boost_1_62_0") # either set it here or from the command line
find_package(Boost 1.62.0 REQUIRED COMPONENTS json) # header only libraries must not be added here
add_executable(tryBoost main.cpp)
I try to find json, but error reported:
No header defined for json; skipping header check
case 2:
cmake_minimum_required(VERSION 3.15)
project(tryBoost)
set(CMAKE_CXX_STANDARD 14)
set(BOOST_ROOT "D:\\cygwin64\\home\\yubo\\boost_1_62_0") # either set it here or from the command line
find_package(Boost 1.62.0 REQUIRED COMPONENTS system) # header only libraries must not be added here
add_executable(tryBoost main.cpp)
I try to find system, but error reported:
Could NOT find Boost (missing: Boost_INCLUDE_DIR system)
How boost organizes its components in sub dirs? How find_package command works when scaning boost root dir? why "header only libraries must not be added here".
thanks.
Please use below CMakeList.txt for reference.

Unable to find the requested Boost libraries boost_lboost_thread

I have been trying to run a Qt project in a CMake environment. The Qt project is using openCV and Boost dependencies. After successfully solving all compiling errors, I have been struggling with a Boost error.
As soon as I run CMake I get the following error:
Running "/usr/bin/cmake /home/labrat/Desktop/cam-proc '-GCodeBlocks - Unix Makefiles'" in /home/labrat/Desktop/cam-proc/build.
**CMake Error at /usr/share/cmake-3.5/Modules/FindBoost.cmake:1677 (message):**

Some (but not all) of the required Boost libraries were found. You may
need to install these additional Boost libraries. Alternatively, set
BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT
to the location of Boost.

I analyzed the error given CMake Error at /usr/share/cmake-3.5/Modules/FindBoost.cmake:1677 (message): and opened the enormous FindBoost.cmake file and here is the part where the error is, according to the warning, located:

I have been googling the error for the past two days looking for information and code to solve this problem, but I am running out of ideas. I tried to download boost 1.55 but it didn't work as the compiler only sees boost 1.58.
Any idea on how to shed light on this matter? Is there something I am leaving out?
The problem is the line
find_package(Boost COMPONENTS filesystem lboost_thread system REQUIRED)
which should be changed to
find_package(Boost COMPONENTS filesystem thread system REQUIRED)
or simply deleted, since it is then equivalent to the following line.

Link boost libraries statically using CMake in CLion

CLion 1.2, with bundled CMake 3.3.2 and MinGW-w64 4.8.4
I need to get a single DLL in a result of building that no need any other libraries to work. But can't link Boost libraries statically. I bootstrapped and built Boost with corresponding MinGW.
cmake_minimum_required(VERSION 3.3)
project(SampleProject)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(BOOST_ROOT "..\\lib\\boost_1_59_0")
set(Boost_USE_STATIC_LIBS ON)

include_directories(${Boost_INCLUDE_DIR})
set(SOURCE_FILES main.cpp)
set(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} -Wl,--kill-at -static-libgcc -static-libstdc++")
add_library(${CMAKE_PROJECT_NAME} SHARED ${SOURCE_FILES})
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}\\..\\..\\output")
target_link_libraries(${CMAKE_PROJECT_NAME} ${Boost_LIBRARIES})
Build output:

O:\SampleProject\Cpp\lib\boost_1_59_0/libs/filesystem/src/operations.cpp:286: undefined reference toboost::system::system_category()'
What else should I do to link with boost?
UPDATE: there is a list of built libraries
libboost_filesystem-mgw48-1_59.a
libboost_filesystem-mgw48-d-1_59.a
libboost_filesystem-mgw48-mt-1_59.a

libboost_system-mgw48-sd-1_59.a
This looks like a linker error suggesting that you are not linking to Boost::system
You need to add system to BOOST_COMPONENTS_NEEDED. Change this line and see if it helps
set(BOOST_COMPONENTS_NEEDED system filesystem )

How to link boost using cmake on windows

the StackOverFlow community!
I'm trying to link up boost libraries and there's an error of linking up the 'boost_system' static library.
I use cmake 2.8, the MinGW compiler and the 1.55.0 boost.
Judging by the logs, cmake doesn't see the pathway to the libraries.
Here's the error:
Unable to find the requested Boost libraries.
Boost version: 1.55.0
Boost include path: c:/local/boost_1_55_0
Could not find the following static Boost libraries:
boost_system
No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the
directory containing Boost libraries or BOOST_ROOT to the location of
Boost.
Call Stack (most recent call first):
Here's the cmake code:
cmake_minimum_required(VERSION 2.8)
project(test)
if (WIN32)
set(BOOST_ROOT "c:/local/boost_1_55_0")
set(BOOST_LIBRARYDIR ${BOOST_ROOT}/stage/lib/)
set(Boost_USE_STATIC_LIBS ON)
set(Boost_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(Boost 1.55 COMPONENTS system REQUIRED)
add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -static-libgcc -static-libstdc++")
include_directories(${Boost_INCLUDE_DIR})
set(SOURCE_FILES main.cpp)
add_executable(test ${SOURCE_FILES})
target_link_libraries(test ${Boost_LIBRARIES})
endif (WIN32)
I receive logs like this with the declared set(Boost_DETAILED_FAILURE_MSG on)
status** Boost Include: c:/local/boost_1_55_0
status** Boost Libraries:
status** Boost Libraries:
For me worked setting hint variables CMAKE_INCLUDE_PATH & CMAKE_LIBRARY_PATH. BOOST_ROOT & BOOST_LIBRARYDIR were not working also.
Another hint variables are Boost_COMPILER, Boost_NAMESPACE, Boost_ARCHITECTURE they help to define how your library is named to boost search script.
Using SET(Boost_DEBUG 1) helped me a lot do diagnose a problem -as it prints Boost path suffixes= and _boost_LIBRARY_SEARCH_DIRS_RELEASE
For example
SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "D:/boost/boost_1_70_0")
SET(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} "D:/boost/boost_1_70_0/stage/gcc/x64/lib")
SET(Boost_COMPILER ${Boost_COMPILER} "-mgw73")
SET(Boost_NAMESPACE ${Boost_NAMESPACE} "libboost")
SET(Boost_ARCHITECTURE "-x64")
Or
SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "D:/boost/boost_1_70_0")
SET(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} "D:/boost/boost_1_70_0/stage/lib")
SET(Boost_COMPILER ${Boost_COMPILER} "-vc142")

Cmake error when adding Boost library

I am trying to add Boost library to my project using the CMakeLists.txt in the follwing way:
set(BOOST_INCLUDEDIR "C:/boost_1_57_0")
set(BOOST_LIBRARYDIR "C:/boost_1_57_0/stage/lib")
find_package(Boost 1.57.0 COMPONENTS filesystem)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(test test.cpp)
target_link_libraries(test ${Boost_LIBRARIES})
However, I get the followng error: LINK : fatal error LNK1104: cannot open file 'libboost_filesystem-vc120-mt-1_57.lib'
libboost_filesystem-vc120-mt-1_57.lib is located in the stage/lib folder, so I don't know what is going on. I am compiling with Visual Studio 2013.
Any thoughts?
Try setting the Boost_USE_STATIC_LIBS and Boost_USE_MULTITHREADED CMake variables to ON before using find_package, i.e.:
set( Boost_USE_STATIC_LIBS ON )
set( Boost_USE_MULTITHREADED ON )
find_package( Boost 1.57.0 COMPONENTS filesystem )
I've come across this problem before and it seems as though, on multithreaded windows systems, the Boost bootstrap installer compiles multithreaded, static libraries by default. However, the CMake FindBoost script (which is used by find_package) searches for single-threaded, dynamic libraries by default.
Since you're using VS compiler I'll say you're working on Windows.
The error refers to the linker, which is failing to find boost libraries, as noticed.
Taking into account that the library exists in the boost path, my solution was to do a file(COPY) for the specific library, as a last resort.
if(WIN32)
set(BOOST_ROOT "C:/boost_1_57_0")
set(BOOST_LIBRARYDIR ${BOOST_ROOT}/stage/lib/)
endif()
find_package(Boost 1.57.0 EXACT REQUIRED system filesystem)
if(Boost_FOUND)
message(STATUS "found boost, Boost_LIBRARIES <" ${Boost_LIBRARIES} ">")
include_directories(${Boost_INCLUDE_DIRS})
link_directories(${Boost_LIBRARY_DIRS})
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
else()
message(STATUS "boost not found")
endif()
target_link_libraries(boost_test ${Boost_LIBRARIES})
file(COPY "${Boost_LIBRARY_DIRS}/boost_filesystem-vc120-mt-1_57.dll" DESTINATION "${CMAKE_CURRENT_BINARY_DIR}")
You may add some log messages to the CMake in order to know the values returned in the
find_package.
Make sure the architecture (x64) matches.
$ cmake -A x64 ..
Use link_directories command before adding executables just like include_directories.
link_directories(${Boost_LIBRARY_DIRS})
