    Are you using CMAKE_PREFIX_PATH as @VRonin suggested ?

      Yes, i have it in the code

          message (STATUS "Defaulting to Linux build environment.")
          set(CMAKE_INCLUDE_CURRENT_DIR ON)
          set( CMAKE_PREFIX_PATH =/usr/lib)
        #  file(WRITE "${LIBROSCO} )#${CMAKE_STATIC_LIBRARY_PREFIX}librosco ${CMAKE_STATIC_LIBRARY_SUFFIX}so*" )
          find_library([${LIBROSCO}]
                       HINTS /usr/lib)
      
      
          # check if we found the library
           message(STATUS "LIB_ROSCO:${LIBROSCO}")
            message(PATH "LIB_ROSCO:${LIBROSCO}")
      
          target_link_libraries (${PNAME} ${LIBROSCO} Qt5::Widgets)
      

      this didn help so I exported the command and have it there```
      leopold@leopold-Mint:~$ export
      declare -x CINNAMON_VERSION="4.4.8"
      declare -x CMAKE_PREFIX_PATH="/usr/lib"
      declare -x COLORTERM="truecolor"

      declare -x GTK_MODULES="gail:atk-bridge"
      declare -x GTK_OVERLAY_SCROLLING="1"

      no help again
      and have it as rwx/rwx/rwx in /usr/lib
      
      still:
      

      Defaulting to Linux build environment.

        @Leopold said in cmake in linux ubuntu:

        find_library([${LIBROSCO}]

        This is wrong. See the documentation - you need to pass a variable, not the content of a variable

          @Leopold said in cmake in linux ubuntu:

          set( CMAKE_PREFIX_PATH =/usr/lib)

          That's an invalid path.

              @VRonin said in cmake in linux ubuntu:

              use find_package(librosco)

              You are using find_library that tryes to link to a dll (which is already wrong) and it contains no infos on the dependancies


              set( CMAKE_PREFIX_PATH =/usr/lib)

              Remove this line, it just creates a mess as it might remove search paths. CMAKE_PREFIX_PATH should be set on the command line (if you are using Qt Creator you have to set it in the project configuration, on the left vertical bar, the wrench icon). /usr/lib is already in PATH so you should actually do nothing

                Hi VRonin
                I did that```
                set(CMAKE_INCLUDE_CURRENT_DIR ON)
                find_package(librosco)
                # check if we found the library
                message(PATH "LIB_ROSCO: ${librosco}" )
                message(STATUS "LIB_ROSCO:${librosco}" )

                how do i have to write the message command

                  If I configure directly with cmake I get this error:

                  CMake Warning at CMakeLists.txt:234 (find_package):
                    By not providing "Findlibrosco.cmake" in CMAKE_MODULE_PATH this project has
                    asked CMake to find a package configuration file provided by "librosco",
                    but CMake did not find one.
                  
                    Could not find a package configuration file provided by "librosco" with any

                    "librosco_DIR" to a directory containing one of the above files.  If
                    "librosco" provides a separate development package or SDK, be sure it has
                    been installed.

                    I can not find those files myself. Do I have to add a command in the cmakelists.txt for librosco

                        I have no folder /usr/lib/librosco but
                        in /usr/lib there are the three librosco.so ,librosco.so.2 and librosco.so.2.0.0
