GDALOpenEx - not found Windows build #102

Closed ashnair1 closed 2 years ago

ashnair1 commented 2 years ago

I've been trying to build ctb on a Windows machine for the last few days and keep running into this error.

For context, I've installed gdal (v3.4.1) via conda. Following are my build logs:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

Looking at the error log, it seems this is caused by -lgdal not being found. I've tried explicitly specifying the path but it didn't work. Hope someone can point me in the right direction.

Issue was solved by using MSVC compiler instead MinGW since that's what was used to package gdal (from conda-forge)
