Undefined Reference to TGUI functions

[thephysicist]

Hello,

I'm using Linux Mint, installed TGUI via the manual on the tutorial page and get this from my cmake file

-- Found SFML 2.4.2 in /usr/include
-- Found TGUI 0.8.6 in /usr/lib/x86_64-linux-gnu/cmake/TGUI
-- Configuring done
-- Generating done

When I try to get the example program, I get the following errors:

undefined reference to `tgui::Gui::Gui(sf::RenderWindow&)'
undefined reference to `tgui::Gui::handleEvent(sf::Event)'
undefined reference to `tgui::Gui::draw()'

I tried compiling with C++17 and C++14.

Are you linking with tgui?
In cmake that would be like "target_link_libraries(your-target PRIVATE tgui)".
