I included this fix but it doesn’t help. I was building the georaster
driver as a plugin but the linker failed at building gdal library. So
the fix doesn’t seem to be related to the problem.
You can't build the driver as a plugin with internal libjpeg. CMake
should prevent you from doing that because of
https://github.com/OSGeo/gdal/blob/master/frmts/georaster/CMakeLists.txt#L6
But I now remember (thanks git blame!) that during the defered driver
loading RFC development, I found that the condition to check that was
broken. This was fixed in

Not the answer you'll probably want to hear, but:
- Use an up-to-date compiler
- Use package distributions like vcpkg or conda-forge that already
brings all the dependencies "for free"
- It seems you mix builds of different compilers (VS vs mingw).
That's a bit asking for troubles ;-)

Resend with more information:
I am trying to build GDAL 3.8.4 on windows under VS2015. The
build failed at linking stage that a bunch of external symbols
not found, specifically the symbols in libproj, libcurl. I
checked the dll library stub .lib for libproj and libcurl
using “dumpbin” and found the symbols in the library a little
different, for example the linker error shows
“__imp__curl_slist_append” not found, the symbol output from
the “dumpbin” is “__imp_curl_slist_append” .
Any idea how to fix this?
Thanks!

GDAL 3.8.4 build on Windows from VS2015 x64 command prompt:
“cmake –build .” throws the following error (there are more
similar errors):
cpl_vsil_az.obj : error LNK2001: unresolved external symbol
__imp__curl_slist_append [E:\gdal-3.8.4\build\GDAL.vcxproj]
cmake options has:
set (GDAL_USE_CURL ON CACHE BOOL "" FORCE)
set (CURL_INCLUDE_DIR
"E:/SDK/curl-8.6.0_1-win64-mingw/include" CACHE PATH "" FORCE)
set (CURL_LIBRARY_RELEASE
"E:/SDK/curl-8.6.0_1-win64-mingw/bin/libcurl-x64.lib" CACHE
FILEPATH "" FORCE)
libcurl-x64.lib is the DLL stub. Using dumpbin on
libcurl-x64.lib shows that “__imp_curl_slist_append” is
available. But the linker error is “__imp__curl_slist_append”
not found. There is an extra “_” in it.
Any idea why this error occurred?
Thanks!
