[QUESTION] Install KISS-Matcher in Window environment (using Power Shell)

[LimHyungTae]

Here, I would like to document how to resolve the issues encountered when installing KISS-Matcher in a Windows environment.

Step 1. Install Visual Studio 2022

Follow the below link:

https://learn.microsoft.com/en-us/cpp/build/vscpp-step-0-installation?view=msvc-170

To install the C/C++ and CMake, Visual Studio is required (I'm not sure if it is necessary, but at least my laptop, it worked)

Step 2. I encountered the following error:

CMake Error at CMakeLists.txt:4 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.


CMake Error at build/_deps/robin-src/cmake/DownloadProject.cmake:171 (message):
  CMake step for pmc failed: 1
Call Stack (most recent call first):
  build/_deps/robin-src/cmake/DownloadExternal.cmake:17 (download_project)
  build/_deps/robin-src/CMakeLists.txt:51 (robin_download_pmc)

Hi @LimHyungTae, thank you very much for your work, it s a hell of a good code and clean one. The problem what you are encountering is that pmc is linux only library, so robin cannot be installed. I was trying to fix it but didn't have time yet. I think during this week I could propose some solution.

@LimHyungTae, one more question: do you think I should try to contact the authors of PMC or create a new repository? Because I've already implemented the Windows version, but it looks like their repo is dead, last commit 8 years ago. Thanks for reply :).

@tom-jurov there is an open pull request in ROBIN to make pmc optional. It is based on this one https://github.com/navidmahmoudian/ROBIN/tree/remove-pmc-dependency
I was able to build ROBIN successfully without pmc, but then ran into issues in compiling the KISS-Matcher, I am using msvc. Let me know if you have any progress.

[tom-jurov]

@hirenpatel1207 I've noticed it, but it isn’t still integrated into the official repo. I managed to rewrite pmc and then used atomics from your mentioned pull request and made everything work using msvc. The KISS-Matcher works like magic.

@tom-jurov Thanks for the reply.
is it possible for you to share the changes that you made and steps for compiling the project using msvc?
I am already able to build ROBIN with msvc, but the problem is with KissMatcher.hpp.
There, I get error like
error C2535: 'std::vector<Eigen::VectorXf,std::allocator<Eigen::VectorXf>> kiss_matcher::KISSMatcher::__attribute__(void)': member function already defined or declare error C2065: 'ssize_t': undeclared identifier
Do we have to set any flags or anything when using msvc? I am using VS 17.2.
