Undeclared EIGEN_STL_UMAP error when building from source

[nnop]

Hi, guys. I'm building pycolmap from source and met many error of undeclared EIGEN_STL_UMAP:

/home/nnop/codes/pycolmap/reconstruction/camera.cc:22:22: error: ‘EIGEN_STL_UMAP’ was not declared in this scope; did you mean ‘EIGEN_OS_MAC’?                                                                                    
  22 | PYBIND11_MAKE_OPAQUE(EIGEN_STL_UMAP(colmap::camera_t, colmap::Camera));                                                                                                                                                  

I searched the source code of colmap and Eigen and didn't find any declaration of EIGEN_STL_UMAP.
BTW, I've installed the latest version of colmap(commit 079b8ad).
My env: Ubuntu 20.04, libeigen3-dev.

Can't figure out where does the problem come from. Looking forward for your help.

It is the recent colmap commit, which breaks the pycolmap...

Thanks for the hint.
I found It's colmap PR#1947 that Remove unnecessary custom Eigen aligned allocator macros breaks the pycolmap compilation.

Until that PR goes through, my workaround was to checkout and build with commit 9eddf2e4; release 3.8 is too old and suffers from Issue 1742, and the current dev branch is waiting on colmap PR#1947, but the linked commit is new enough to avoid the former and old enough to avoid the latter.
