I'm getting following error while building akonadi :

ankit@ankit-SVE15116ENB:~/akonadi/build$ cmake ..
CMake Error at CMakeLists.txt:6 (find_package):
Could not find a package configuration file provided by "ECM" (requested
version 5.14.0) with any of the following names:

ECMConfig.cmake
ecm-config.cmake

Add the installation prefix of "ECM" to CMAKE_PREFIX_PATH or set "ECM_DIR"
to a directory containing one of the above files. If "ECM" provides a
separate development package or SDK, be sure it has been installed.


-- Configuring incomplete, errors occurred!

Please someone suggest me some solution to this problem.
