I want to use the latest MeshLab from source because of an annoying bug which makes it impossible to use MeshLab with any locale setting where "," is used instead of "." as decimal separator. Like my German one.
This comes in the README.txt file at the meshlab/src directory:
To compile MeshLab and all MeshLab plugins:
First compile the needed external libraries
qmake -recursive external.pro
then compile MeshLab and its plugins
qmake -recursive meshlab_full.pro
Alternatively you can directly compile only a subset of the whole meshlab by using the meshlab_mini.pro. This minimal subset does not require any external library (give a look at the .pro itself for more info).
qmake -recursive meshlab_mini.pro
For more complete info, please, refer to the meshlab wiki:
