Add empty list of sources to add_library and add_executable.

Remove 2.6-isms
Remove 2.8-isms
Bump CMake minimum version to 3.4

Disable some options when used as a subdirectory

Use `CONFIGURE_DEPENDS` with `file(GLOB)` when possible

Backport CMake 3.15's MSVC_RUNTIME_LIBRARY setting.
Set all compile options as generator expressions.
Set all find-package files to be installed to the correct file.

Remove `export(PACKAGE)`, as this has been deprecated.
Remove fat binary support
Remove manual setting of iPhone settings. These should be set by parent
projects.
Remove use of ExternalProject for a local use
Conditionally remove format target unless clang-format is found

Setting CMAKE_CXX_STANDARD and CMAKE_CXX_STANDARD_REQUIRED directly is problematic when including yaml-cpp as a subproject.

The proper way is to set these per-target.

Roll-forward of c90c08cc "Revert "Improvements to CMake buildsystem (#563)""

NEW:

* Replace CMAKE_SOURCE_DIR with CMAKE_CURRENT_SOURCE_DIR

Fixes #612 when yaml-cpp is used as a git submodule.

ORIGINAL:

* Move enable_testing() into proper place

* Added CMake's checks for C++11 standards

Raised minimal version of CMake to 3.1, since on old systems there no
decent compilers that supports c++11.

Closes #377.

* Externalize googletest project

Externalize gtest to avoid installation, fixes #539.

* Remove defined cmake_policies

CMP0012 - OLD marked as deprecated for >=cmake-3.1 and will be removed
CMP0015 - does not affect to build process
CMP0042 - already NEW for >=cmake-3.1

Fixes #505

* Fix compiling in Windows MSVC

This reverts commit 3e33bb31.

The original commit broke the build (#612) when yaml-cpp is used as a git submodule.

* Fix compiling in Windows MSVC

Note that with the release of 1.8.0, googlemock and
googletest are unified into a single release.

Fix for broken build on cygwin using gcc - "error '[fileno, strdup, fdopen]' are not in scope" (#374)

 - Adds 'std=c++11' compiler flags
 - Replaces boost::type_traits with std::type_traits
 - Replaces boost::shared_ptr with std::shared_ptr
 - Replaces std::auto_ptr with std::unique_ptr
 - Replaces raw pointers with std::unique_ptr in ptr_vector, ptr_stack, and SettingChanges
 - Replaces boost::noncopyable with deleted copy and assignment operators
 - Replaces boost::next with std::next
 - Replaces boost::enable_if with std::enable_if
 - Replaces boost::is_convertible with std::is_convertible
 - Replaces ptrdiff_t with std::ptrdiff_t
 - Replaces boost::iterator_facade and boost::iterator_adaptor with std::iterator, borrowing the 'proxy reference' technique from boost
 - Removes Boost dependency from CMakeLists
 - Formats changed files using clang-format

Fix clang compiler settings, and properly set up warnings so they don't interfere with gtest and gmock
