Updated the version from 1.1 to 1.2
Renamed the header to "Slint Royalty-free Desktop, Mobile, and Web Applications License"
Added definition of "Mobile Application" and grant of right
Moved "Limitations" to 3rd section and "License Conditions - Attributions" to 2nd section
Added flexibility to choose between showing "MadeWithSlint" as a dialog/splash screen or on a public webpage
Moved the para on copyright notices to section under "Limitations"
two bugs:
- If the .slint file did not contain any import, the depfile would have
no dependencies, and as a result, ninja would consider that it is
always dirty.
- In case the binary dir is a sub directory, the dependencies were
relative to the wrong directory. Thgis is because the behavior
changed in some version of cmake (see https://cmake.org/cmake/help/latest/policy/CMP0116.html)
to avoid any problem, use the absolute paths
Fixes#3261
