[Pkg-cmake-team] Bug#853028: Bug#853028: cmake does not find bzip2 (libbz2)

[Enrico Lumetti]

Sure, these are the two that I've tried:

cmake_minimum_required(VERSION 3.7)
project(bug)
find_package (BZip2)
if(NOT BZIP2_LIBRARIES)
   message("bzip2 not found")
endif()

its output:
-- Could NOT find BZip2 (missing:  BZIP2_LIBRARIES BZIP2_INCLUDE_DIR)
bzip2 not found

This one with find_library:
cmake_minimum_required(VERSION 3.7)
project(bug)

find_library(BZ2_LIBRARY bz2 libbz2)
if(NOT BZ2_LIBRARY)
   message("bzip2 not found")
endif()

Output: bzip2 not found
