Error: version '408*', prefer 'B32*'

Describe the bug
When I'm trying to run gcovr I'm getting this huge message:

(ERROR) GCOV produced the following errors processing /Users/rachelsa/Downloads/matrix_cpp/build/tester/complement.cpp.gcda:
	Trouble processing '/Users/rachelsa/Downloads/matrix_cpp/build/tester/complement.cpp.gcda' with working directory '/Users/rachelsa/Downloads/matrix_cpp/build/tester'.

Manual calling of gcov with flags gives something like that:

GaussElimination.cpp.gcno:version '408*', prefer 'B32*'
GaussElimination.cpp.gcno:no functions found

To Reproduce
Steps to reproduce the behavior:

1. I have the following CMakeLists.txt file:

cmake_minimum_required(VERSION 3.14)
project(my_project)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_FLAGS --coverage)

include(FetchContent)
FetchContent_Declare(
  googletest
  URL https://github.com/google/googletest/archive/03597a01ee50ed33e9dfd640b249b4be3799d395.zip
)

set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)

enable_testing()

add_executable(
  main
  ./tests/test.cpp
  ./srcs/arithmetic.cpp
  ./srcs/determinant.cpp
  ./srcs/inverse.cpp
  ./srcs/complement.cpp
  ./srcs/transpose.cpp
  ./srcs/operators.cpp
  ./tools/print_matrix.cpp
  ./tools/GaussElimination.cpp
  ./tools/ResizeMatrix.cpp
)
target_link_libraries(
  main
  GTest::gtest_main
)

include(GoogleTest)
gtest_discover_tests(main)

2. In ./matrix_cpp/ directory I have all of the header and .cpp files
3. I also have this Makefile to run CMake:

OPS=		./srcs/arithmetic.cpp \
				./srcs/complement.cpp \
				./srcs/determinant.cpp \
				./srcs/inverse.cpp \
				./srcs/transpose.cpp

TOOLS=	./tools/print_matrix.cpp \
				./tools/GaussElimination.cpp \
				./tools/ResizeMatrix.cpp

TESTS=	./tests/test.cpp

SRCS=		$(OPS) $(TOOLS)

OBJS=		$(SRCS:.c=.o)

.PHONY: clean s21_matrix_oop.a gcov_report test
all: clean

test: s21_matrix_oop.a
	@rm -rf build
	@mkdir build
	@cd build && cmake ../ && make && ./main

4. I run (it passes all my tests and creates build dir where It creates executable and .gcda/.gcno files:

make test

5. After this command I get an error:

gcovr -r .

Expected behavior
I expected that I'll got coverage - but I've got nothing, but errors.

Desktop (please complete the following information):

• OS: [macOS Ventura 13.5]
• GCC version [13.2.0]
• GCOVR version [7.2]
• Project directory layout:
  • Main Working Directory: ./matrix_cpp/
  • Executable and gcno/gcda files located in: ./matrix_cpp/build

I would be happy to any help and any links to similar problems, 'cause I didn't find nothing similar.
Thanks! :3

Can you post your command line? The message [Errno 2] No such file or directory: '/path/to/correct/gcov' shows that a wrong gcov tool is configured.

Have you tried the option --verbose?
