    Hi I did the sudo make install in the librosco build folder there it was the makefile
    adding to LD_LIBRARY_PATH was activated.
    I do not know where it is installed.

    @Leopold said in cmake in linux ubuntu:

    I do not know where it is installed

    You should see the path in the output of "make install"

          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)

                target_link_libraries (${PNAME} ${LIBROSCO} Qt5::Widgets)
            

            this didn help so I exported the command and have it there```

            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

                That's an invalid path.

                    As I said:

                    @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:

                          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
