Windows Windows dependencies install failed via ```script\install-deps-windows.bat```

[short435]

Issue:

Dependencies install failed via script\install-deps-windows.bat according to the vcpkg.

Test environment:

OS: Windows G2O version: Latest vcpkg version: Latest with commit '6b6a35335c9064fac2ec6684c4f79808dce59b7d'

I try to build g2o from source by using the the vcpkg to install the dependencies. However it seems having some package conflict form these dependencies. It's there any vcpkg commit were already been tested and able to build your repo. It will be great if you can provide a vcpkg commit(version tag) which is buildable.

Output:

Im not actively using Windows. It might be not working, this bat file. vcpkg --triplet x64-windows install eigen3 Would be the minimal requirement to compile. See also https://github.com/RainerKuemmerle/g2o/blob/master/.github/workflows/windows.yml

I have come across the same problem as @Shortz79 . I have tried to remove clapack and install lapack-reference. It works well! However, I cannot install Clapack after that because of conflicts.

Realized that this is the same as in https://github.com/RainerKuemmerle/g2o/issues/638 Is there any known way to install suitesparse with vcpkg that works at the moment? I would appreciate feedback from Windows users.

Clapack and lapack-reference conflict with each other. Suitesparse requires lapack-reference on windows while g2o requires clapack. Check https://github.com/microsoft/vcpkg/blob/master/ports/lapack/vcpkg.json Lapack uses lapack-reference !(arm & windows) and I don't quite understand why. Building g2o with lapack-reference rather than clapack will raise a error. I guess editing vcpkg/ports/lapack/vcpkg.json will help but I didn't do the test.
