If you're not using jom on Windows then you can stop reading here.
There's a new version of jom available at https://download.qt.io/official_releases/jom/jom_1_1_4.zip Changes since jom 1.1.3 - Fixed handling of the command line option /j. - Makefiles that do not contain targets are allowed. - Fixed handling of macro definitions on the command line (QTCREATORBUG-22176). - Enabled usage of paths longer than MAX_PATH (QTCREATORBUG-22848). - Added version information to the executable (QTCREATORBUG-23290). - Fixed directory separators in the MAKEDIR variable (QTCREATORBUG-23559). - Fixed expansion of absolute path wildcard dependencies (QTCREATORBUG-26745). - Fixed performance penalty when checking for dependency cycles in complex Makefiles (QTCREATORBUG-29412).
