Cannot find boost include directories when add boost via FetchContent

Question

I'm trying to add boost library to my project via FetchContent.

In my CmakeLists.txt i wrote:

FetchContent_Declare(
    boost
    GIT_REPOSITORY https://github.com/boostorg/boost.git
    GIT_TAG        master
)
FetchContent_MakeAvailable(boost)
include_directories(${Boost_INCLUDE_DIRS})

But when i'm trying to include something from boost i'm getting error. Include example:

#include <boost/container/flat_set.hpp>

Error:

C:/rep/OrderBook/src/orders/Order.h:14:10: fatal error: boost/container/flat_set.hpp: No such 
file or directory
   14 | #include <boost/container/flat_set.hpp>
