And I use this CMake to use gcovr in my project.
but when i execute 'make coverage' command. It always give below error back:
C:\Downloads\gcovr-3.2\gcovr -r C:/Test/src --object-dir= C:/Test/build -e test_*
process_begin: CreateProcess(NULL, C:\Downloads\gcovr-3.2\gcovr -r C:/Test/src --object-dir= C:/Test/build -e test_*, ...) failed.
