[SOLVED] building OpenCV as deb package: CPackDeb: file utility is not available

Issue

I'm building OpenCV 4.1 as a deb package on Ubuntu 18.04. After success in building libraries. I'm calling make package and getting the following error:

CPack: Create package CMake Error at /usr/share/cmake-3.10/Modules/CPackDeb.cmake:622 (message): CPackDeb: file utility is not available. CPACK_DEBIAN_PACKAGE_SHLIBDEPS and CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS options are not available. Call Stack (most recent call first): /usr/share/cmake-3.10/Modules/CPackDeb.cmake:1119 (cpack_deb_prepare_package_vars)

Does anybody have any ideas on how to fix it?

Solution

Just need to install file package: apt install file
