Krita

[contact . ng0]

I'm not sure if someone was/is working on this, but here's a patch you can
use as a start.

I could probably fix it, but I drop work on this.
Here's the error to get you started on fixing it:

CMake Error at CMakeLists.txt:208 (find_package):
  By not providing "FindECM.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "ECM", but
  CMake did not find one.

  Could not find a package configuration file provided by "ECM" (requested
  version 1.7.0) 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.
