Require libevent_core not libevent for pkg-config libevent library itself had been deprecated long time ago. Fixes: #1213 2022-03-10 23:58:36 +03:00			`Requires: libevent_core`
Make dependency paths relocatable The generated configurations for both CMake and pkg-config included absolute paths to dependencies (OpenSSL, MbedTLS). This is contrary to the general CMake advise to create relocatable packages [1]. Additionally, when building both mbedtls and libevent via CMake's FetchContent in the same project, loading the project would fail with INTERFACE_INCLUDE_DIRECTORIES property contains path: "/home/user/project/cmake-build/_deps/mbedtls-build/include" which is prefixed in the source directory. The required changes include: - Adding the outer includes only to the BUILD_INTERFACE solves the makes the CMake paths relocatable and thus solves the FetchContent problem. - Updates to libevent_*.pc.in fixes the relocatable issues for pkg-config and properly declares currently missing dependencies. - Using components for linking to OpenSSL (requiring CMake 3.4) and MbedTLS. The new MbedTLS target names now match the component names of the MbedTLS' CMake project. - Use the Threads CMake library reference instead of a direct reference to support both built-in pthread and -lpthread. v2 (azat): get back CMAKE_REQUIRED_LIBRARIES [1] https://cmake.org/cmake/help/v3.25/manual/cmake-packages.7.html#creating-relocatable-packages 2022-12-01 18:39:52 +01:00			`Requires.private: libssl`
