Add a clangd make target:
$ make clangd
This installs a .clangd file with configuration (includes/macros/compiler flags)
for the clandg language server.
Add a qtcreator make target:
$ make qtcreator
This installs a .qtcreator directory with QTCreator IDE project files.
In the QTCreator you can open a project by selecting the .qtcreator/morm.creator
file.
You can use 'make qtcreator' again to refresh .qtcreator/morm.files,
the rest of the project files will not be modified.
