Yes, i have it in the code

Now my question: Is this caused by an other entry in the cmakelists file?

@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
-
-
As I said:
@VRonin said in cmake in linux ubuntu:
use find_package(librosco)
You are using
find_librarythat 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_PATHshould 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/libis already inPATHso you should actually do nothing -
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 of the following names: libroscoConfig.cmake librosco-config.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. PATHLIB_ROSCO: LIB_ROSCO: Configuring done -
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
