[QA] generic build instrutions are incomplete

[jnweiger]

I've tried to compile master on ubuntu 22.10 -- which seems pretty good in providing most of the cmake dependencies
like qt5, qtkeychain, ecm with usable versions.

The build gets stuck with

CMake Error at src/libsync/CMakeLists.txt:1 (find_package):
  By not providing "FindLibreGraphAPI.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "LibreGraphAPI", but CMake did not find one.

  Could not find a package configuration file provided by "LibreGraphAPI"
  (requested version 1.0.4) with any of the following names:

    LibreGraphAPIConfig.cmake
    libregraphapi-config.cmake

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

There seems to be no Ubuntu dev package for this.

I've looked into the documentation,
https://doc.owncloud.com/desktop/4.0/appendices/building.html#generic-build-instructions
It does not mention libre graph api.

After some research,
the missing LibreGraphAPIConfig.cmake file can built from owncloud/libre-graph-api repo but then cmake it fails with

  include could not find requested file:

    /mnt/libre-graph-api/out/cpp/client/LibreGraphAPITargets.cmake

Hello @jnweiger,

You can surpass this error with the same steps:

1 - git clone https://github.com/KDAB/KDSingleApplication.git
2 - cd KDSingleApplication/
3 - cd cmake
4 - cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX=/usr -G Ninja
     ninja install -v 
5 - cd ../../
6 - rm -rf KDSingleApplication
7 - sudo ldconfig

Once all is set and done, run > cmake .. on {owncloud_client_sourcecode}/client/client-build/

For me its asking a .a file but what is built for me is a .dylib.
Also, the name and locations are different.
