Hi @lbhack ! Thanks for the feedback. This issue has been solved in NAppGUI 1.3 (will be released next 26/12/2022).

For now, you can fix it adding these lines at the end of targetLinkWithLibraries function in /prj/CMakeFunctions.txt

# In GCC the g++ linker must be used
if (${CMAKE_SYSTEM_NAME} STREQUAL "Linux" OR ${CMAKE_SYSTEM_NAME} STREQUAL "Darwin")
    set_target_properties(${targetName} PROPERTIES LINKER_LANGUAGE CXX)
endif()

I close this issue because compile testing in Ubuntu 22.04 with NAppGUI 1.3 works fine. Also in other Ubuntu versions. Please reopen if still you have problems with this.
