• OS: NixOS
• OS Version: 24.11 (Vicuna)
• Architecture: amd64

git describe
3.3.0-entrypoint-106-g1080995fa4

Steps to reproduce

On a system with clang compiler run:

mkdir build && cd build && cmake -DENABLE_GCOV=ON ../

Actual behavior

CMake Error at cmake/profile.cmake:17 (message):
  ENABLE_GCOV option requested but gcov library is not found
Call Stack (most recent call first):
  CMakeLists.txt:79 (include)

Expected behavior

cmake finishes successfully, tarantool can be built with gcov support afterwards.
