Feature: Build for windows

[mounte]

Current problem

Currently this is not easily built on windows (I have not yet succeded at least.) Adding windows build instructions and potentially CMakePreset that sets necessary flags if needed would be welcomed.

Hi @mounte , doesn't this example work for you? https://www.reduct.store/docs/next/getting-started/with-cpp#installing-the-c-sdk . Could you provide logs so I can help you quickly and update the documentation?

Out of the box following

cmake -S . -B build -DREDUCT_CPP_USE_STD_CHRONO=ON

results in:

CMake Error at cmake/InstallDependencies.cmake:3 (find_package):
  By not providing "Findfmt.cmake" in CMAKE_MODULE_PATH this project has

  CMake did not find one.

  Could not find a package configuration file provided by "fmt" with any of
  the following names:

    fmtConfig.cmake

  Add the installation prefix of "fmt" to CMAKE_PREFIX_PATH or set "fmt_DIR"
  to a directory containing one of the above files.  If "fmt" provides a
  separate development package or SDK, be sure it has been installed.

This is with conan executable being found. If I on the other hand force it to not find conan

 cmake -S . -B build -DREDUCT_CPP_USE_STD_CHRONO=ON  -DCONAN_CMD=""

it can generate the project files... but when building it fails due to openssl

So there is the openssl issue, I usually rely on the vcpkg deps for openssl, so not sure what the intended way here is to find a good inclusion of the openssl lib.
By installing from: https://slproweb.com/products/Win32OpenSSL.html (it installs to: C:\Program Files\OpenSSL-Win64 )
actually makes it build (openssl needs to be installed before configuring the project)

So I guess the roadblocker I hit was that cmake did not complain, there should probably be a find_package openssl required?

Then there is this warning:
cl : command line warning D9002: ignoring unknown option '-fPIC'

I think what should be used is:
set_property(TARGET thelib PROPERTY POSITION_INDEPENDENT_CODE ON)
which as far as I recall sets the right flag for compiler/linker.
