That file isn't part of the Exiv2 distribution. I believe it's part of MinGW and although MinGW executables are intended to run on "Native Windows" without additional DLLs, clearly that promise is not being. On my Windows 10 machine, I have the following copies of that file:

c:\cygwin64\user\i686-w64-mingw32\sys-root\mingw\bin\libwinpthread-1.dll
c:\cygwin64\user\x86_64-w64-mingw32\sys-root\mingw\bin\libwinpthread-1.dll
c:\cygwin64\usr\i686-w64-mingw32\sys-root\mingw\bin\libwinpthread-1.dll
c:\cygwin64\usr\x86_64-w64-mingw32\sys-root\mingw\bin\libwinpthread-1.dll
c:\Program Files (x86)\Microsoft Visual Studio\2017\...\libwinpthread-1.dll
c:\Program Files (x86)\PhotoQt\libwinpthread-1.dll

I've also used the depends32.exe tool (which is in the Exiv2 code base) to inspect for other DLLs which you may need:

$ msvc/tools/bin/depends32 /q $(cygpath -aw /c/temp/dist/mingw/bin/exiv2.exe)
bcryptPrimitives.dll
CRYPTBASE.dll
SspiCli.dll
RPCRT4.dll
WS2_32.dll
SHELL32.dll
PSAPI.DLL
zlib1.dll
GDI32.dll
win32u.dll
USER32.dll 
KERNELBASE.dll
ntdll.dll
KERNEL32.dll
libexpat-1.dll
libexiv2-26.dll
  Not found: libstdc++-6.dll

  Not found: libstdc++-6.dll
  Not found: libgcc_s_dw2-1.dll
511 rmills@rmillsmbp-w7:/c/users/rmills/gnu/exiv2/0.26 $

I'm a little surprised by those dependancies. These DLLs are readily available on-line.

For your information, I have found MinGW to be a very troublesome build environment and will not be supporting it in future. During the last year, I've talked to the Engineers at darktable who strongly advocate msys2. I'm hoping to find the motivation and time to work on that soon. If you're interested in this, I'm always looking for volunteers to join the team. If you'd like to support Exiv2/MinGW,/MSYS I will be happy to mentor you and give you encouragement.
