Instructions for updating the CMake build files

Remove setting the output directories in the root CMakeLists.txt

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
Suppress the deprecation warnings in non-MSVC compilers in the root CMakeLists.txt

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Wnon-virtual-dtor -Wno-deprecated-declarations")
Add in the new custom target that only builds the libraries (not zello_world) to the root CMakeLists.txt

add_custom_target(libraries_only)
add_dependencies(libraries_only ze_loader ze_null ze_tracing_layer ze_validation_layer)
Remove any and all instances of setting the target properties in all CMakeLists.txt, so we have .so files without the version appended, e.g.

set_target_properties(${TARGET_LOADER_NAME} PROPERTIES
VERSION "${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}.${PROJECT_VERSION_PATCH}"
SOVERSION "${PROJECT_VERSION_MAJOR}" )
