FindGIF.cmake
We use the version from CMake now. There is a minor difference, which will not affect many systems. The KDE version accepted only giflib version 4, while the CMake version accepted any version of giflib. If giflib version 4 .x is required, the version can now be specified:
- find_package(GIF) -> find_package(GIF 4 )
This actually only was an issue on some relatively old Sun machines in 2006. Maybe today it is not even there a problem anymore.
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
MacroAddCompileFlags.cmake
This file has been removed. Use set_property(.. APPEND_STRING) instead (new in CMake 2.8.6).
- include(MacroAddCompileFlags) -> delete
- macro_add_compile_flags(target "-O2 -g") -> set_property(TARGET target APPEND_STRING PROPERTY COMPILE_FLAGS " -O2 -g")
MacroAddLinkFlags.cmake
This file has been removed. Use set_property(.. APPEND_STRING) instead (new in CMake 2.8.6).
- include(MacroAddLinkFlags) -> delete
- macro_add_link_flags(target "-no-rpath") -> set_property(TARGET target APPEND_STRING PROPERTY LINK_FLAGS " -no-rpath")
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()
