This creates and installs a package version file and a package config
file. These are used by find_package with the CONFIG option, and are
roughly equivalent to pkgconfig, but is cmake specific rather than linux
specific.
v2: - Use configure_package_config_file() instead of config_file(),
which generates helper macros and resolves relative paths allowing
the entire install to be moved.
- Update WaffleConfig.cmake.in to take advantage of
configure_package_config_file()
- Use SameMajorVersion instead of AnyNewerVersion for version
compatibility. Since waffle uses apache's numbering scheme 2.0.0
should not fulfill a requirement of 1.5.0 and vice versa.
v3: - Use CMAKE_BINARY_DIR (Jordan)
- Move generation of cmake config to the same area of the cmake file
as pkgconfig
