Hi,
I was running into an annoying bug recently and tried to fix it myself. However, I can't get CMake to run properly right out of the master branch. There are what looks to me obvious errors in the CMake scripts, but I thought as these haven't been changed recently, I'm most likely doing something wrong.
Here is my output when running cmake on the current master branch (URLs in output stripped due to validator in this forum):

-- Configuring incomplete, errors occurred!
The errors start with FindSphinx not found. This is totally understandable, as build/_deps/ecm-src/CMakeLists.txt is not built to be imported as a module. See line 36:
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake")This does obviously not work and should be
set(CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/cmake")But on the other hand, if this is (as I understand it) a widely used CMake scripts collection by the KDE team, it is probably not meant to be used by CMake's FetchContent.
So, how am I supposed to compile QET?
Thanks,
Christoph
