I have been trying for several days to install OpenCV with Conan (on Windows 10). However, the installation is failing on building the libjpeg/9d dependency.
Conan profile:
[settings]
arch=x86_64
arch_build=x86_64
build_type=Debug
compiler=gcc
compiler.libcxx=libstdc++11
compiler.version=8
os=Windows
os_build=Windows
[options]
[build_requires]
[env]
The used command:
conan install .. --profile vslamprofile --build=missing
The part of the logs related to the error:
libjpeg/9d: configure: creating ./config.status

libjpeg/9d: config.status: creating libjpeg.pc

I have found several people with the similar error (not while installing OpenCV though) but I have not managed to find any solution.

It is very possible that the libjpeg library doesn't compile with autotools and/or makefiles in the MinGW tool suite. Even if it is a gcc for Windows, it is not like all the code is fully portable between platforms, and those autotools or Makefiles might do some assumptions of platform that are not correct in Windows.
In general, the Visual Studio toolchain (MSBuild, cl.exe) is better supported in Windows platforms by the community, could be considered the default to-go, especially nowadays that the Visual Studio Community editions are completely free.
The packages in ConanCenter are also typically (and most of them, the ones created from the conan-center-index repo) built and tested with Visual Studio (several versions), so the support is expected to be much better than the one for MinGW.
