MinGW64 missing dependency mingw-w64-x86_64-libraw

[tanolino]

I was trying to follow the build tutorial on https://rawpedia.rawtherapee.com/Windows but the cmake failed to configure my project and complained about:

-- Checking for module 'libraw_r>=0.21'
--   Package 'libraw_r' not found
CMake Error at Z:/msys64/mingw64/share/cmake/Modules/FindPkgConfig.cmake:645 (message):
  The following required packages were not found:

   - libraw_r>=0.21

So I had to install one additional dependency, using pacman -S mingw-w64-x86_64-libraw

Actually, the instructions should not include -DWITH_SYSTEM_LIBRAW="ON". The internal LibRaw is preferred. The LibRaw dependency is only required when the system LibRaw option is set.
