I'm trying to link my project to various boost libraries (thread, system, program_options, filesystem, and date_time). I'm using CLion's bundled MinGW, and have used Vcpkg to install my required libraries, and added the requirements to vcpkg.json. CLion seems to have handled all of this well, and from what I can tell, I've done everything correctly - the libraries are all built and installed locally, and exist, the headers are found, etc. From all the documentation and other StackOverflow posts I can find, I'm doing everything correctly, but, the project refuses to link successfully.
Here is my CMakeLists.txt. Things which are commented out are various things I've tried to make this work.
cmake_minimum_required(VERSION 3.25)
project(myproject)
set(CMAKE_CXX_STANDARD 17)
# (I've tried various combinations of these to no avail)
# set(Boost_USE_STATIC_LIBS ON)
# set(Boost_USE_MULTITHREADED ON)
# set(Boost_USE_STATIC_RUNTIME ON)
# set(Boost_ARCHITECTURE -x64)
# set(Boost_USE_STATIC_LIBS OFF)
find_package(Boost REQUIRED COMPONENTS program_options system thread filesystem)
message("Boost libraries: ${Boost_LIBRARIES}")
include_directories(
${Boost_INCLUDE_DIR}
lib/libmyproject/include
include)
add_library(libmyproject STATIC
lib/libmyproject/source/libmyproject.cpp)
add_executable(myproject
source/myproject.cpp)
#link_libraries(${Boost_LIBRARIES})
#target_link_libraries(myproject -static)
#target_link_libraries(myproject ${Boost_LIBRARIES})
#target_link_libraries(myproject Boost::thread Boost::program_options Boost::system)
target_link_libraries(myproject ws2_32 ${Boost_LIBRARIES})
This is the output that CLion gives from CMake:

The library files outputted by my message() all exist, and are built, and seem to be valid in every way. CMake seems to find them just fine, and the boost libraries are passed to the linker. The linker command is as follows:
cmd.exe /C "cd . && C:\PROGRA~1\JETBRA~1\CLION2~1.4\bin\mingw\bin\G__~1.EXE -g CMakeFiles/myproject.dir/source/myproject.cpp.obj -o myproject.exe -Wl,--out-implib,libmyproject.dll.a -Wl,--major-image-version,0,--minor-image-version,0 -lws2_32 vcpkg_installed/x64-windows/lib/boost_thread-vc140-mt.lib vcpkg_installed/x64-windows/lib/boost_program_options-vc140-mt.lib vcpkg_installed/x64-windows/lib/boost_system-vc140-mt.lib vcpkg_installed/x64-windows/lib/boost_chrono-vc140-mt.lib vcpkg_installed/x64-windows/lib/boost_atomic-vc140-mt.lib -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32 && cmd.exe /C "cd /D D:\devel\repositories\myproject\cmake-build-debug && C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noprofile -executionpolicy Bypass -file C:/Users/myprofile/.clion-vcpkg/vcpkg/scripts/buildsystems/msbuild/applocal.ps1 -targetBinary D:/devel/repositories/myproject/cmake-build-debug/myproject.exe -installedDir D:/devel/repositories/myproject/cmake-build-debug/vcpkg_installed/x64-windows/debug/bin -OutVariable out""
This fails however, with various references to undefined boost symbols across all the boost libraries I need to link. I'll spare the question the long output, but, for example:
