Linker error when I try to built in visual studio when I try to create other project including the directories of these project #51

As this has no visual studio project in it. I created a new project and created the example file. I included the directories of the dependency headers. But I am getting linker error 1>Source.obj : error LNK2019: unresolved external symbol "unsigned long cdecl asio::detail::win_tss_ptr_create(void)" (?win_tss_ptr_create@detail@asio@@YAKXZ) referenced in function "public: cdecl asio::detail::win_tss_ptr<class asio::detail::call_stack<class asio::detail::thread_context,class asio::detail::thread_info_base>::context>::win_tss_ptr<class asio::detail::call_stack<class asio::detail::thread_context,class asio::detail::thread_info_base>::context>(void)" (??0?$win_tss_ptr@Vcontext@?$call_stack@Vthread_context@detail@asio@@Vthread_info_base@23@@detail@asio@@@detail@asio@@QEAA@XZ) 1>Source.obj : error LNK2019: unresolved external symbol "class std::error_category const & cdecl asio::system_category(void)" (?system_category@asio@@YAAEBVerror_category@std@@XZ) referenced in function "class std::error_category const & cdecl asio::error::get_system_category(void)" (?get_system_category@error@asio@@YAAEBVerror_category@std@@XZ) 1>Source.obj : error LNK2019: unresolved external symbol "public: cdecl asio::system_context::~system_context(void)" (??1system_context@asio@@QEAA@XZ) referenced in function "public: void * __cdecl asio::system_context::`scalar deleting destructor'(unsigned int)" (??_Gsystem_context@asio@@QEAAPEAXI@Z) 1>Source.obj : error LNK2019: unresolved external symbol "protected: static void cdecl asio::detail::winsock_init_base::startup(struct asio::detail::winsock_init_base::data &,unsigned char,unsigned char)" (?startup@winsock_init_base@detail@asio@@KAXAEAUdata@123@EE@Z) referenced in function "public: cdecl asio::detail::winsock_init<2,0>::winsock_init<2,0>(bool)" (??0?$winsock_init@$01$0A@@detail@asio@@QEAA@_N@Z) 1>Source.obj : error LNK2019: unresolved external symbol "protected: static void cdecl asio::detail::winsock_init_base::cleanup(struct as

I had similiar errors - first occurence was: Link: C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29910\bin\HostX64\x64\link.exe /ERRORREPORT:QUEUE /OUT:"G:\Fyo_tests\CppServer\temp\RelWithDebInfo\cppserver-example-https_server.exe" /INCREMENTAL /NOLOGO ..\modules\OpenSSL\VS\lib\libssl.lib ..\modules\OpenSSL\VS\lib\libcry pto.lib "C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x86\Crypt32.Lib" "C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x86\MsWSock.Lib" "C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x86\WS2_32.Lib" modules\CppCommon\RelWithDebInfo\cppcommon.lib RelWithDebInfo\cppserv er.lib "C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x86\Crypt32.Lib" "C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x86\MsWSock.Lib" "C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x86\WS2_32.Lib" modules\CppCommon\RelWithDebInfo\cppcommon.lib "C:\Program Files (x86) \Windows Kits\10\Lib\10.0.18362.0\um\x86\DbgHelp.Lib" "C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x86\RpcRT4.Lib" "C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x86\UserEnv.Lib" modules\CppCommon\modules\RelWithDebInfo\fmt.lib modules\RelWithDebInfo\asio.lib ..\modules\OpenSSL\ VS\lib\libssl.lib ..\modules\OpenSSL\VS\lib\libcrypto.lib kernel32.lib user32.lib gdi32.lib winspool.lib shell32.lib ole32.lib oleaut32.lib uuid.lib comdlg32.lib advapi32.lib /MANIFEST /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /manifest:embed /DEBUG /PDB:"G:/Fyo_tests/CppServer/temp/RelWithDebInfo/ cppserver-example-https_server.pdb" /SUBSYSTEM:CONSOLE /TLBID:1 /DYNAMICBASE /NXCOMPAT /IMPLIB:"G:/Fyo_tests/CppServer/temp/RelWithDebInfo/cppserver-example-https_server.lib" /MACHINE:X64 /machine:x64 "cppserver-example-https_server.dir\RelWithDebInfo\https_server.obj" 19>cppcommon.lib(uuid.obj) : error LNK2019: Verweis auf nicht aufgelöstes externes Symbol "__imp_UuidCreate" in Funktion ""public: static class CppCommon::UUID __cdecl CppCommon::UUID::Random(void)" (?Random@UUID@CppCommon@@SA?AV12@XZ)".

As you will notice, the link.exe is being run from x64 folder, while libs are being used from C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x86 => the lib path is wrong!

In build\VisualStudio\01-generate.bat you can see cmake -DCMAKE_INSTALL_PREFIX=../temp/install -G "Visual Studio 16 2019" -A x64 .. So C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x64 would have been correct on my machine for the lib files.

SOLUTION: before running vs.bat I had to run the following SET CMAKE_LIBRARY_PATH=C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x64 (check if this is the correct path on your machine!)

Why isn't that environment variable set in the vs.bat script?
