Bug 124555 – [EFL] Use Config mode of find_package for EFL 1.8

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Ryuan Choi]

EFL 1.8 changed VERSION macro so it's difficult to use tricky approach which parses header file to know the VERSION.
Instead, EFL 1.8 supports Config mode of find_package using XXXConfig.cmake such as EinaConfig.cmake

So, we can use Config mode of find_package when we found Eo (which is introduced since EFL 1.8).

Looks fine except for some English nits.

> Source/cmake/OptionsEfl.cmake:130
> +    # EFL 1.8 provide XXXConfig.cmake

- provide -> provides ? 
- XXXConfig -> FooConfig.

> Tools/ChangeLog:8
> +        * MiniBrowser/efl/CMakeLists.txt: Introduced Config mode to find elementary.

Config mode -> a config mode ?

> ChangeLog:12
> +        This patch try to use Config mode if it is available after checked Eo.

try -> tries ? 
after checked -> after checking ?

It seems like 'CONFIG' option of find_package() is supported on cmake 3.8.8 or later.
But the minimum required version of cmake is 2.8.3.

Error : 
CMake Error at Source/cmake/OptionsEfl.cmake:126 (find_package):
  find_package called with invalid argument "CONFIG"

Ubuntu 12.04 (the latest LTS) is shipped with cmake 2.8.7,
I don't think if we should drop supporting this release.

Ryuan will find a better way to support this mode.

Seokju, could you check with newer patch.
I believe that it will be solved.

Sure, I don't want to drop them.

Instead, I changed little bit.

Eo will not be checked with config mode by removing legacy FindEo.cmake.
And added QUIET not to print warning.
To support EFL 1.8 with cmake lower than 2.8.8, I supposed to use legacy FindFoo.cmake without version requirement because Eo will guarantee the version.

[Seokju Kwon]

LGTM with EFL 1.7
Thanks.

Isn't there CMAKE_VERSION_VERSION_MORE or similar thing ? It looks this is double *not not* condition. If there is no similar thing, this is fine.

Unfortunately cmake only have VERSION_LESS, VERSION_EQUAL, VERSION_GREATER.
So, below is another option but also complicated.
if ((CMAKE_VERSION VERSION_GREATER 2.8.8) OR (CMAKE_VERSION VERSION_EQUAL 2.8.8))
