Can't build: Failed to find some components and more

[igorcafe]

I was having this issue:

$ cmake -S . -B build 
CMake Error at src/CMakeLists.txt:2 (find_package):
  Found package configuration file:

    /usr/lib64/cmake/Qt6/Qt6Config.cmake

  but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT
  FOUND.  Reason given by package:

  Failed to find Qt component "Quick".

  Expected Config file at "/usr/lib64/cmake/Qt6Quick/Qt6QuickConfig.cmake"
  does NOT exist

  Failed to find Qt component "QuickControls2".

  Expected Config file at
  "/usr/lib64/cmake/Qt6QuickControls2/Qt6QuickControls2Config.cmake" does NOT
  exist


-- Configuring incomplete, errors occurred!
See also "/home/igor/Git/unofficial-discord-client/build/CMakeFiles/CMakeOutput.log".
See also "/home/igor/Git/unofficial-discord-client/build/CMakeFiles/CMakeError.log".

So I just created the files it wasn't finding and ran again:

$ cmake -S . -B build
-- Configuring done
CMake Error at src/CMakeLists.txt:44 (add_executable):
  Target "unofficial-discord-client" links to target "Qt6::Quick" but the
  target was not found.  Perhaps a find_package() call is missing for an
  IMPORTED target, or an ALIAS target is missing?

If you try

mkdir build
cd build
cmake ..
cmake --build .

?

The folder was created:

$ ls -l build

drwxr-xr-x 4 igor igor 4,0K out 14 17:09 src

I removed it and tried what you said, but I got the same last error message.
I believe it may be some dependecy missing, since it couldn't find Quick and QuicKControls2 components.

Yes it seems related to your Qt6 installation... Maybe try to build an empty project with QtQuick in order to catch the problem
