Could not find the following Boost libraries: boost_system

Question

I want to build this repository: https://github.com/reo7sp/tgbot-cpp.

It is an API for managing Telegram bots. The needed dependencies are openssl, zlib, boost. Curl is optional.

How I installed libraries and cmake

Boost was compiled with:

bootstrap.bat
.\b2

and (since I do not know the difference; one compiles under boost/stage/lib; the second under boost/lib)

bjam install --prefix=D:/Programme/Boost/boost_1_69_0 --with-system --with-date_time --with-random link=static runtime-link=shared threading=multi

I added the required paths in system variables under path.

environment variables

Path

When trying to build with cmake I get the following error:

It seems to me that everything except of Boost works. I know that there are several users with this problem like:

Cmake doesn't find Boost

CMake with Boost could not find static libraries

CMake with Boost library Windows 10 Library not found correctly

So, I did the suggested procedures:

SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "D:/Programme/Boost/boost_1_69_0")
SET(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} "D:/Programme/Boost/boost_1_69_0/lib")

FIND_PACKAGE(Boost)
IF (Boost_FOUND)
    INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIR})
    ADD_DEFINITIONS( "-DHAS_BOOST" )
ENDIF()

and

set(BOOST_LIBRARYDIR D:/Programme/Boost/boost_1_69_0/lib)

Nothing worked. I have absolutely no clue what to do, for days desperately trying to figure out what to do without success. Please, help me.

Solution

Use the same command to build and install Boost.

bjam install --prefix=D:/Programme/Boost/boost_1_69_0 --with-system --with-date_time --with-random link=static runtime-link=shared threading=multi

In windows, Boost creates another sub directory under include. It should be something like this.

D:/Programme/Boost/boost_1_69_0/include/boost-1_69

Move all files in D:/Programme/Boost/boost_1_69_0/include/boost-1_69 to D:/Programme/Boost/boost_1_69_0/include/

(Move the contents up to one directory)

Now set the BOOST_ROOT in CMake project to D:/Programme/Boost/boost_1_69_0.

It should work now.

by default, Cmake looks for the boost libraries in stage/lib (i did not change anything manually): imgur.com/q5Tx3ug

after I have set "Boost_DIR" to "D:\Programme\Boost\boost_1_69_0" and click on "configure" cmake states again Boost_DIR --> "Boost_DIR-NOTFOUND": imgur.com/JQNWg1Y

Obviously something is wrong with either your install or your variables. This has always worked out of the box on any configuration I used.

[Spixmaster]

absolutely works! Thank you very much. It took like 20 hours for me to look for a solution..
