Hi,.
I have in my windows environment variables (not in any other place) this one:

PROJ_LIB = C:\dev\vcpkg\vcpkg\buildtrees\proj\x64-windows-rel\data
Attached I send what is in this folder.

I think it could be the cause of the problem, but I'm not an expert.
Luck and tell us if I solve anything :)

Hi,

I'm trying to build the GDAL dll and lib files, so GDAL can be used for linker and includes in an other C++ project. We're needing to upgrade from GDAL 3.2.2 to 3.8.3. I try to create project file for VS 2019. In GDAL 3.2.2 was for that purpose used "generate_vcxproj.bat", which was in root directory. Now, this file is no there anymore. For that reason I try to do it with CMake program. But when I did it from cmd as " cmake -G "Visual Studio 16 2019" " or directly from Cmake, I got an error messages like this ...

CMake Error at C:/Program Files/CMake/share/cmake-3.28/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find PROJ (missing: PROJ_LIBRARY PROJ_INCLUDE_DIR) (Required is at least version "6.0")

Call Stack (most recent call first):
  C:/Program Files/CMake/share/cmake-3.28/Modules/FindPackageHandleStandardArgs.cmake:600 (_FPHSA_FAILURE_MESSAGE)
  cmake/modules/packages/FindPROJ.cmake:57 (find_package_handle_standard_args)
  cmake/helpers/CheckDependentLibraries.cmake:378 (find_package)
  gdal.cmake:265 (include)
  CMakeLists.txt:246 (include)

>From my point of view, it seems, that this is most important "Could NOT find PROJ (missing: PROJ_LIBRARY PROJ_INCLUDE_DIR)
(Required is at least version "6.0")". Where and how I have to set that ? If I put that as Environment variables in CMake program like
PROJ_INCLUDE_DIR = -IC:\OSGeo4W\include
PROJ_LIBRARY = C:\OSGeo4W\lib
it did not work.
