Error with cmake

[aposuit]

I copied the commands indicated in readme, with the following error. I do not understand how to solve it.

cd KDE-Rounded-Corners; mkdir qt5build; cd qt5build; cmake ../ -DCMAKE_INSTALL_PREFIX=/usr -DQT5BUILD=ON && make && sudo make install && (kwin_x11 --replace &)

CMake Error at CMakeLists.txt:10 (find_package):
  Could not find a package configuration file provided by "ECM" 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.

Thanks for the help.

What is your distribution and does it distributeextra-cmake-modules?

[aposuit]

Thanks. I use Manjaro. With "pacman -S extra-cmake-modules" the problem was resolved.

Thanks for bringing this up. I added dependencies list for debian based distros to the readme.

Thanks. I use Manjaro. With "pacman -S extra-cmake-modules" the problem was resolved.

I am happy to help but for your convenience, this was the 3rd result on google ;)

I can confirm, although this is closed, that installing the extra cmake modules works. Building from scratch now works 100%.
