==

General purpose expression templates library for C++20.

Intended mostly for CFD and other HPC applications. 

Building

--------

    cmake -B build -DCMAKE_BUILD_TYPE=Release

    cmake --build build

Run the examples:

    ./build/et_test

    ./build/derivative_test

Including into your project

---------------------------

Option one: use cmake `add_subdirectory` assuming you have downloaded ET source code into 

`external/et`:

    add_subdirectory(external/et)

then link your executable to `et` library

    add_executable(my_executable)

    target_link_library(my_executable PRIVATE et)
