the CLion IDE (version 2021.2.3). It should compile using other IDEs (like XCode) without any
issues.

Install command line build tools:
$ xcode-select --install

We recommend using Homebrew to install the dependencies:
https://brew.sh

All dependencies may then be installed from the command line:

$ brew install pugixml
$ brew install boost
$ brew install qt5
$ brew install jsoncpp

Make sure that QTDIR is set to the base qt folder containing the bin and lib dirs, while Qt5_DIR
should be set to the folder containing the Qt5Config.cmake file (typically $QTDIR/lib/cmake/Qt5/).

There is no default support for OpenMP as it is not supported by Apple clang (version 13.0.0).
The following environment variables should be set (for instance in your .bashrc file if you are
using bash):
- QTDIR should be set to the base qt folder containing the bin and lib dirs, typically
/opt/homebrew/opt/qt5/.
- BOOST_ROOT should be set to the directory containing the boost include and lib directories,
typically /opt/homebrew/opt/boost/.

OpenMP is not natively supported by Apple clang (version 15.0.0). It may however be enabled by
installing the LLVM OpenMP library:
$ brew install libomp

Set the following environment variables (add to .bashrc if you are using bash):
export CC=/usr/bin/clang
export CXX=/usr/bin/clang++
export CPPFLAGS="$CPPFLAGS -Xpreprocessor -fopenmp"
export CFLAGS="$CFLAGS -I/opt/homebrew/opt/libomp/include"
export CXXFLAGS="$CXXFLAGS -I/opt/homebrew/opt/libomp/include"
export LDFLAGS="$LDFLAGS -Wl,-rpath,/opt/homebrew/opt/libomp/lib -L/opt/homebrew/opt/libomp/lib -lomp"
