0_setup_env.sh: this script installs all the required dependencies that are necessary to build MeshLab and to create its DMG in a MacOS machine (tested in 10.15 Catalina). It requires homebrew installed;
1_build.sh: this script builds MeshLab in a MacOS environment:
- it requires a properly set Qt environment (see 0_setup_env.sh);
- takes as arguments:
  - the build directory (default: src/build): --build_path=path/to/build
  - the install directory (default: src/install): --install_path=path/to/install
  - the number of cores used to build MeshLab (default: -j4)`
  - the possibility to build MeshLab with double precision scalar: --double_precision
2_deploy.sh: this script makes portable a meshlab.app appdir. Takes as arguments:
- the path where the output install path of the 1_build.sh script is placed (default: src/install): --install_path=path/to/install
3_dmg.sh: this script generates a DMG that can be used to install MeshLab. Takes as arguments:
- the path where the install path of the 2_deploy.sh script is placed (default: src/install): --install_path=path/to/install
- if MeshLab has been built with double precision scalar, add: --double_precision
make_it.sh: this script builds, deploys and generates a DMG that can be used to install MeshLab. Arguments are the same of the 1_build.sh script.

Examples

Building MeshLab on a clean MacOS environment (build placed in meshlab/src/build):

git clone --recursive https://github.com/cnr-isti-vclab/meshlab
sh meshlab/scripts/macOS/0_setup_env.sh
sh meshlab/scripts/macOS/1_build.sh

Building and generating a DMG on a clean MacOS environment:

build directory: ./meshlab-build
install directory: ./meshlab-install
DMG path: ./

git clone --recursive https://github.com/cnr-isti-vclab/meshlab
sh meshlab/scripts/macOS/0_setup_env.sh
sh meshlab/scripts/macOS/make_it.sh --build_path="./meshlab-build" --install_path="./meshlab-install"
