## Build MeshLab
MeshLab builds with the three major compilers: `gcc`, `clang`, and `msvc`. It requires [Qt](https://www.qt.io/) >= 5.15.

After setting up the Qt environment:
git clone --recursive https://github.com/cnr-isti-vclab/meshlab
mkdir meshlab/src/build
cd meshlab/src/build
cmake ..
make
```
git clone --recursive https://github.com/cnr-isti-vclab/meshlab
mkdir meshlab/src/build
cd meshlab/src/build
cmake ..
make
```
You can also use [QtCreator](https://www.qt.io/product) to build meshlab:
1. Install QtCreator and Qt >= 5.12;
1. Install QtCreator and Qt 5.15;
2. Open `CMakeLists.txt` inside `src`;
3. Select your favourite shadow build directory;
4. Build meshlab.
MeshLab has a plugin architecture and therefore all the plugins are compiled separately; some of them are harder to be compiled. Don't worry: if a plugin fails to compile, just remove it and you lose just that functionality.
### Platform specific notes
On __osx__ some plugins exploit openmp parallelism (screened poisson, isoparametrization) so you need a compiler supporting it and the clang provided by xcode does not support openmp. You can install all the required libraries by running the following command in a terminal:
brew install llvm libomp
```
brew install llvm libomp
```
On __Windows__, we suggest to build meshlab using QtCreator. Before trying to build, you should:
* install VisualStudio >= 2017 with the C++ development package;
* install Qt >= 5.12 and QtCreator.
* install Qt 5.15 and QtCreator.
then, open the CMakeLists.txt file and try to build MeshLab.
