Review request for Extra Cmake Modules and David Faure.


Repository: extra-cmake-modules


Description
-------

With CMake 3.1, @-style variable expansion is deprecated outside of
configure_file() or string(CONFIGURE) contexts (CMP0053). This causes
ecm_generate_pri_file() to produce dev warnings with this verison of
CMake, and would break this function in projects that set CMake 3.1 as
their required version.


Diffs
-----

  modules/ECMGeneratePriFile.cmake b353e867586346a10e0f8df77b81ff83993ae497 

Diff: https://git.reviewboard.kde.org/r/121971/diff/


Testing
-------

Attica still configures and builds, and produces the same .pri file it did before.


Thanks,

Alex Merry
