I don't understand what is benefit when we install EWebLit(2)Confit.cmake to /lib/cmake/EWebKit.

Now, there are two options for applications to use ewebkit(2).
First option is using pkg_config_modules. It will check ewebkit(2).pc
Second option is makind their own FindEWebKit.cmake such as what we did internally for cairo, libsoup and other modules.

Although CMake provide pkg_check_modules(first option) but it's not preferred.
Instead, cmake applications like find_package(XXX) but it's a burden for applications that each applications add their own FindXXX.cmake.

If we provide EWebKit(2)Config.cmake, applications can use find_package(EWebKit(2) ..).

I see. BTW, I wonder how can application know this location(lib/cmake/EWebKit(2)) to get EWebKit2Config|Version.cmake.

applications doesn't need to know, but they probably gave prefix.(default prefix is /usr and /usr/local)

Then, find_package() will search several directories including it from given prefix.

http://www.cmake.org/cmake/help/v2.8.10/cmake.html#command:find_package

<prefix>/(lib/<arch>|lib|share)/cmake/<name>*/ is first and good location on unix system.
