mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_RELEASE_TYPE=Release ..
cmake --build . 
cmake --install .

Build options:

• BUILD_EXAMPLE - build example CLI app (OFF by default)
• BUILD_TESTING - build tests (ON by default)

Usage

Add these lines to your CMakeLists.txt:

find_package(PwCard REQUIRED)
target_link_libraries(sample_project PwCard::pwcard)

Then include <pwcard/pwcard.h> in your code:

#include <pwcard/pwcard.h>

void print_password_card(uint64_t number)
{
    auto pwcard = PwCard::generate(number);
    std::cout << PwCard::to_utf8(pwcard.header) << std::endl;
    for (auto &&row : pwcard.rows)
        std::cout << PwCard::to_utf8(row) << std::endl;
}
