# this is a script shell for compiling meshlab in a Linux environment.
# Requires a Qt environment which is set-up properly, and an accessible
# cmake binary.
#
# Without given arguments, MeshLab will be built in the meshlab/src/build
# directory, and installed in $BUILD_PATH/../install.
# 
# You can give as argument the BUILD_PATH and the INSTALL_PATH in the 
# following way:
# sh linux_build --build_path=/path/to/build --install_path=/path/to/install
# -b and -i arguments are also supported.

#default paths wrt the script folder
