[package] zlib/1.2.11: cmake find_package generates wrong filename

Package and Environment Details (include every applicable attribute)

• Package Name/Version: zlib/1.2.11
• Conan version: conan 1.19.1
• Python version: Python 3.7.4

Conan profile

[settings]
os=Linux
os_build=Linux
arch=x86_64
arch_build=x86_64
compiler=gcc
compiler.version=8
compiler.libcxx=libstdc++
build_type=Release

[env]

Steps to reproduce (Include if Applicable)

Create conanfile.txt with contents:

[requires]
boost/1.71.0

[generators]
cmake_find_package
cmake_paths

CMakeLists.txt:

include(${CMAKE_BINARY_DIR}/conan_paths.cmake)

find_package(boost REQUIRED)

Run

$ mkdir build && cd build
$ conan install ..
$ cmake ..

Expected: boost is found by CMake.

Actual:

By not providing "Findzlib.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "zlib", but
  CMake did not find one.

I’m pretty sure this is the offending commit: https://github.com/conan-io/conan-center-index/commit/eda6295c4d5cfa725bf2f00a7dd15f35c306018c but I suspect there was a reason for making the change. If I rename FindZLIB.cmake to Findzlib.cmake, it finds the package successfully. This is because the generated Findboost.cmake contains this line:

    find_dependency(zlib REQUIRED)

@sztomi I believe this stability guarantee applies to the conan client itself. as for recipes I guess the policy is to be compatible with the latest release https://github.com/conan-io/conan-center-index/wiki

Make sure you are using the latest Conan client version, the recipes might evolve introducing features of the newer Conan releases

@sztomi was your question solved? Can we close this issue? thanks
