Error when building from source

[TruongKhang]

Hi Mr. Sarlin,

Thank you for the great code. I'm a big fan of your works.

I've already installed COLMAP 3.9.1. I'm trying to build the latest version of pycolmap from source. When I run python -m pip install ., the error looks like this:

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for pycolmap
Failed to build pycolmap
ERROR: Could not build wheels for pycolmap, which is required to install pyproject.toml-based projects

I wonder how to fix this issue. Thank you!

Solved in https://github.com/colmap/pycolmap/issues/226:

-- Found SQLite3
  --   Includes : /usr/include
  --   Libraries : /usr/lib/x86_64-linux-gnu/libsqlite3.so

is the log printed by the old, broken FindSQLite3.cmake shipped in COLMAP <= 3.8; CMake>=3.14 ships it own FindSQLite3.cmake, which properly defines the SQLite::SQLite3 target: https://cmake.org/cmake/help/latest/module/FindSQLite3.html Maybe you didn't properly uninstall 3.8 and the file /usr/local/share/colmap/cmake/FindSQLite3.cmake remains?

I'm able to build pycolmap 0.4.0 with colmap 3.8. Just close this issue for now. I'll try to upgrade to pycolmap 0.5.0 and colmap 3.9 in the future, and come back if this issue happens again!
