CMake building a library with ECM

Question

I am trying to build this library https://github.com/KDE/pulseaudio-qt for a custom linux version for an embedded device created with yocto. The SDK yocto produces does not contain the extra-cmake-modules that the library needs to be build. After sourcing the environment setup script of the SDK I tried running cmake on the library:

-- Could NOT find ECM (missing: ECM_DIR)                                                              
--                                                                                                    
 * ECM (required version >= 5.44.0), Extra CMake Modules., <https://kde.org/products/frameworks/>     

CMake Error at /opt/board_sdk/0.6.0/sysroots/x86_64-boardsdk-linux/usr/share/cmake-3.12/Modules/FeatureSummary.cmake:459 (message):

  CMakeLists.txt:9 (feature_summary) 

After that I tried installing the ECM modules manually. They ended up in /usr/share/ECM, so I tried setting ECM_DIR to this location before running cmake with:

export ECM_DIR=/usr/share/ECM

But the same error still occurs. Can somebody assist me in this? I have not tucked into cmake at all at this point.

Answer 1

The following got me past that error:

sudo apt install extra-cmake-modules
