TRIQS is a rather big library that can take a considerable amount of time to compile. We therefore recommend to build and install TRIQS beforehand (see Installation) and then link against it (see find_package).

The following assumes that the project using TRIQS is CMake-based.

CMake

find_package

If you have already installed TRIQS on your system by following the instructions from the Installation page, you can make use of CMake's find_package command.

Let's assume that TRIQS has been installed to path_to_install_dir. Then linking your project to TRIQS with CMake is as easy as

cmake_minimum_required(VERSION 3.20)
project(my_project CXX)
 
# find TRIQS
find_package(triqs REQUIRED CONFIG)
 
# declare a target and link to TRIQS
add_executable(my_executable main.cpp)
target_link_libraries(my_executable triqs)

In case, CMake cannot find the package, you might have to tell it where to look for the TRIQSConfig.cmake file by setting the variable TRIQS_DIR to path_to_install_dir/lib/cmake/triqs or by sourcing the provided triqsvars.sh before running CMake:

$ source path_to_install_dir/share/triqs/triqsvars.sh
