[valgur]

Summary

Changes to recipe: qscintilla/2.14.1

Motivation

QScintilla is a Qt port of the Scintilla text editing component.

Source mirror: https://github.com/brCreate/QScintilla

Details

I initially tried to make the recipe work with the src/scintilla.pro qmake file, but I kept running into issues with the build flags (such as the compiler executable path) not being respected. At the same time, propagating the standard Conan build flags and profile details through an ad-hoc qmake generator was not much simpler or shorter than rewriting it as a CMake project, so I went with the latter option.

Here's a failed attempt at getting the project to build with the original qmake-based build system: https://github.com/valgur/conan-center-index/blob/new/qscinitilla-qmake/recipes/qscintilla/all/conanfile.py#L69-L134

^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
