I am trying to generate a some coverage reports using gcov and gcovr, but gcovr fails to process my files.

The compile line for a particular file is the following

  "command": "/usr/bin/g++-11 -DAPP_VERSION=\"0.0.0\" -DBOOST_ALL_DYN_LINK -DCore_EXPORTS -DFMT_SHARED -DOPENVDB_DLL -DSPDLOG_COMPILED_LIB -DSPDLOG_FMT_EXTERNAL -I/workspace/src/Mandos/Core/../.. -I/workspace/build/ci-x86_64-gcc-11-Debug-gcov/src/Mandos/Core/../.. -isystem /home/dev/.conan2/p/openvdb7d765a96317/p/include -isystem /home/dev/.conan2/p/b/boost4946fa66ec618/p/include -isystem /home/dev/.conan2/p/zlib94980e21071ae/p/include -isystem /home/dev/.conan2/p/onetb4c5f56eddd2b6/p/include -isystem /home/dev/.conan2/p/imath50a3e93596d2e/p/include -isystem /home/dev/.conan2/p/imath50a3e93596d2e/p/include/Imath -isystem /home/dev/.conan2/p/eigen3d88c0279cc26/p/include/eigen3 -isystem /home/dev/.conan2/p/tracy3ca493a7de887/p/include -isystem /home/dev/.conan2/p/spdlob47137badbb6c/p/include -isystem /home/dev/.conan2/p/fmt2942afe02511d/p/include -m64 -g -std=c++20 -fPIC -fvisibility=hidden -fvisibility-inlines-hidden --coverage -O0 -g -pedantic -Wall -Wextra -Wextra-semi -Wshadow -Wnon-virtual-dtor -Wold-style-cast -Wcast-align -Wunused -Woverloaded-virtual -Wpedantic -Wconversion -Wsign-conversion -Wnull-dereference -Wdouble-promotion -Wformat=2 -Wimplicit-fallthrough -Wmisleading-indentation -Wduplicated-cond -Wduplicated-branches -Wlogical-op -Wuseless-cast -Werror -pedantic-errors -o src/Mandos/Core/CMakeFiles/Core.dir/MechanicalStates/Particle3D.cpp.o -c /workspace/src/Mandos/Core/MechanicalStates/Particle3D.cpp",

I run gcovr with the following command in the build directory (/build/ci-gcc-11-Debug-gcov/)

gcovr --xml-pretty --print-summary -o coverage.xml --root ../../

and I get the following error

gcvor version es 7.0

I have no clue what I am doing wrong. How should I fix this?
