FindRUBY.cmake

This file does not exist anymore, use FindRuby.cmake coming with CMake instead. Most variables are the same. Below are the changes:

find_package(RUBY) -> find_package(Ruby)
RUBY_INCLUDE_PATH -> RUBY_INCLUDE_DIRS

MacroAdditionalCleanFiles.cmake

This file has been removed. Use set_property(... APPEND ...) instead.

include(MacroAdditionalCleanFiles) -> delete
macro_additional_clean_files(file1 file2 fileN) -> set_property(DIRECTORY APPEND PROPERTY ADDITIONAL_MAKE_CLEAN_FILES "file1;file2;fileN" )

MacroOptionalAddSubdirectory.cmake

This file is now part of the extra-cmake-modules package and thus has been renamed to ECMOptionalAddSubdirectory.cmake

include(MacroOptionalAddSubdirectory) -> include (ECMOptionalAddSubdirectory)
macro_optional_add_subdirectory(...) -> ecm_optional_add_subdirectory(...)

MacroOptionalDependPackage.cmake

This file has been removed, the purpose was broken.

include (MacroOptionalDependPackage) -> delete
macro_optional_depend_package() -> delete

MacroOptionalFindPackage.cmake

This file does not exist anymore. Instead, starting with CMake 2.8.6, every find_package() call which is not REQUIRED can be disabled by setting the variable CMAKE_DISABLE_FIND_PACKAGE_<PackageName> to TRUE. This makes this macro unnecessary.

include(MacroFindPackage) -> delete
macro_optional_find_package(Foo ...) -> find_package(Foo ... )

MacroPushRequiredVars.cmake

This file has been merged into CMake, but has been renamed to CMakePushCheckState.cmake.

include(MacroPushRequiredVars) -> include(CMakePushCheckState)
macro_push_required_vars() -> cmake_push_check_state()
macro_pop_required_vars() -> cmake_pop_check_state()
