VectorBLF and QXlsx needs internet/git access at build time. We do not want
that. Separate ports might help here. While here disable CMake Git detection.
Spotted by aja and naddy, thanks!
LabPlot is a program for two- and three-dimensional graphical presentation of
data sets and functions. LabPlot allows you to work with multiple plots which
each can have multiple graphs. The graphs can be produced from data or from
functions.
