296: 1112: 1102: 22: 1122: 578:. The developers hoped to eventually push for Qbs to replace qmake as Qt's own build system. However, in October 2018 it was deprecated in favor of qmake and/or cmake. In an August 7, 2019 blog post, the Qt Company stated that starting with Qt 6, cmake will become Qt's standard build system and cited cmake's extreme popularity as a factor. 519:
Each build project contains a single build graph (*.bg) file in the directory where Qbs stores the serialized representation of its internal build graph format. Deserializing this file and utilizing the cached information allows Qbs to very quickly resolve the project, leading to near-instant

Qbs is unique in that it has no mechanism for in-source builds, guaranteeing the ability to create several builds from a single source tree, including building them from a single command invocation and in parallel. This is a key feature, ensuring that source files remain unaffected if a build

Qbs 1.0 was released in 2013 and further developed by the Qt Company beginning around that time under the governance model of the 354:.
