    librosco is built and installed with cmake so it is super easy.
    After you built librosco just call sudo make install then add the path where the library was installed to CMAKE_PREFIX_PATH if it's not a directory already in your PATH variable.
    Now you can just use find_package(librosco)

      Hi Vronin,
      I could install librosco but when I search for the package i get this answer
      :```

      By not providing "FindLIBROSCO.cmake" in CMAKE_MODULE_PATH this project has
      asked CMake to find a package configuration file provided by "LIBROSCO",

      Could not find a package configuration file provided by "LIBROSCO" with any
      of the following names:

      LIBROSCOConfig.cmake

      Add the installation prefix of "LIBROSCO" to CMAKE_PREFIX_PATH or set
      "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.

      when I search for the library i get this fault:
      

      CMake Error at CMakeLists.txt:229 (find_library):
      find_library called with incorrect number of arguments

      the same when i write find_file.
      When i read the man for  find_library or find_file  only one argument is needed , the rest is optional. Am I right?

        @Leopold said in cmake in linux ubuntu:

        I could install librosco

        In what folder?

        I think you missed this part:

        @VRonin said in cmake in linux ubuntu:

        add the path where the library was installed to CMAKE_PREFIX_PATH if it's not a directory already in your PATH variable.

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

                  Are you using CMAKE_PREFIX_PATH as @VRonin suggested ?

                      @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

                              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:

                                  but CMake did not find one.

                                  "librosco" provides a separate development package or SDK, be sure it has

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