Using CPM to add Eigen and OpenXLSX libraries

Usage
1

Hi,

I have a cmake + C++ project where I need both Eigen and OpenXLSX libraries.

According to the readme, the OpenXLSX should build on both windows and linux platforms.

My attempt

I am using CPM, so my main root/CMakeLists.txt is

# add dependencies
include(cmake/CPM.cmake)
CPMAddPackage("gh:gabime/spdlog@1.13.0")
CPMAddPackage("gh:zeux/pugixml@1.14")
CPMAddPackage(
        GITLAB_REPOSITORY libeigen/eigen
        GIT_TAG 3.4
        OPTIONS "EIGEN_BUILD_DOC OFF"
        "EIGEN_BUILD_PKGCONFIG OF"
        "EIGEN_BUILD_DOC OFF"
)
CPMAddPackage("gh:vincentlaucsb/csv-parser#2.2.0")
CPMAddPackage("gh:troldal/OpenXLSX#ededa1e8398305d0983648d3e9f120ff7e228d2b")

Here I added the last line to include a specific commit of OpenXLSX as well.

Problem

While this builds successfully on ubuntu-22.04 with my github actions, it fails miserably on windows latest after adding that single line in CMake.

The output I was able to get says:

YOu can see the now the eigen library suddenly no longer buildsā€¦

Would anybody know what to do?

Iā€™d ask CPM developers; they may have more ways to assist.

Other than that, I would try to strip it down and/or trace why this Eigen message shows up suddenly. Maybe there are cache variables that end up conflicting somewhere?

you should check you label!

you are working with an old version on branch 3.4

IMHO: you need at least version: Reorganize CMake and minimize configuration for non-top-level builds. (!1556) Ā· Merge requests Ā· libeigen / eigen Ā· GitLab

Is it safe to use not-yet-officially-released version?

I intentionally used the latest release.

If you need the Windows build, open a ticket as written.
