how to include Lib without library identification in qmake

[Blackzero]

I want to use the WinLicenseSDK library but the documentation does not provide an example of using the library in qt c++, the documentation only provides sample code C++ Win32 API, can anyone help me how to solve it?

INCLUDEPATH += D:/WinLicense SDK/WinLicenseSDK/Include/C
LIBS += -LD:/WinLicense SDK/WinLicenseSDK/Lib/COFF

error

.......\LicenseMenager\licensemenager.cpp:15: error: C1083: Cannot open include file: 'WinlicenseSDK.h': No such file or directory

@Blackzero Try putting quotes around the paths with spaces.

@ChrisW67 yes it works and can install #include “WinlicenseSDK.h” but there are problems that arise.
I am using MSVC2019 64bit

@ChrisW67 I have found a way to solve the SYSTEMTIME error by adding

#include <Windows.h>
