what is the lib's file name?

I just search the keyword "dwmapi" in my F:\msys2\mingw64\lib folder, I don't see such name matches, instead, there is a file named:F:\msys2\mingw64\include\dwmapi.h

So, my guess is that the library name is not "dwmapi"?
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

Decide which toolchain you are trying to use!
The above shows both "c:/mingw" and "C:/msys64/mingw64" this will normally result in a few weird errors.

Here's what I found about "-ldwmapi"
Code
/*
 * dwmapi.h
 *
 * Some dwmapi.dll exported functions such as
 *   DwmFlush
 *   DwmAttachMilContent
 *   DwmDetachMilContent
 * are not declared in this header for not being documented by Microsoft
 *
 */


#ifndef __WINAPI_DWMAPI_H
#define __WINAPI_DWMAPI_H


#include <wtypes.h>


/* for MARGINS structure declaration.  */
#include <uxtheme.h>


/*
 * This API is available only on Vista+ versions. It's not guarded by version check
 * because that would cause problems with Mozilla code (and MSVC doesn't seem to be
 * doing that as well).
 */


#ifdef __cplusplus
extern "C" {
#endif


/* FIXME: move to winuser.h */
/* DWM messages.  */
#define WM_DWMCOMPOSITIONCHANGED 0x031E
#define WM_DWMNCRENDERINGCHANGED 0x031F
#define WM_DWMCOLORIZATIONCOLORCHANGED 0x0320
#define WM_DWMWINDOWMAXIMIZEDCHANGE 0x0321

Static Linking dwmapi.dll is statically linked to the following files:
msvcrt.dll
ntdll.dll
api-ms-win-core-libraryloader-l1-2-0.dll
api-ms-win-core-synch-l1-2-0.dll
api-ms-win-core-errorhandling-l1-1-1.dll
api-ms-win-core-handle-l1-1-0.dll
api-ms-win-core-heap-l1-2-0.dll
api-ms-win-core-registry-l1-1-0.dll
api-ms-win-core-processthreads-l1-1-2.dll
api-ms-win-core-profile-l1-1-0.dll
api-ms-win-core-debug-l1-1-1.dll

api-ms-win-core-quirks-l1-1-0.dll
api-ms-win-core-delayload-l1-1-1.dll  This means that when dwmapi.dll is loaded, the above files are automatically loaded too. If one of these files is corrupted or missing, dwmapi.dll won't be loaded.

Why do you need "-ldwmapi" if you use GTK?
Here is my project in codeblocks, you can see it as a demo GTK for Windows.
@stahta01 I have used a makefile here, this is my answer to whether it is difficult to use a makefile if I understand you correctly.
