From 6b8ca51e912089acdf84a54c5d60301faf3f7f8f Mon Sep 17 00:00:00 2001 From: Marco Ridoni Date: Thu, 16 Jun 2022 14:30:13 +0200 Subject: [PATCH] - Improved logging support (#15), misc fixes - Improved logging support (uses spdlog) - VS build files now use vcpkg - Linux build fixes - MinGW (32/64) build with autoconf now is fully working, doesn't need qmake anymore --- Makefile.am | 2 +-
