(yes, I came from a Microsoft Visual Studio world) Here is the path to my QT project where I'm trying to use CMake. This directory has one source code file. main.cpp ~/dev/qt_workspace/InitGStreamer$ My QT build folder is here ~/dev/qt_workspace/InitGStreamer/build-InitGStreamer-Desktop_Qt_5_7_0_GCC_64bit-Default$ Then I created a sub directory structure under it. I got this structure from reading the CMake docs. <a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://cmake.org/Wiki/CMake:How_To_Find_Libraries"> https://cmake.org/Wiki/CMake:How_To_Find_Libraries</a> ~/dev/qt_workspace/InitGStreamer/cmake/Modules$ In in there is a file called FindGStreamer.cmake which I found here <a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://raw.githubusercontent.com/WebKit/webkit/master/Source/cmake/FindGStreamer.cmake"> https://raw.githubusercontent.com/WebKit/webkit/master/Source/cmake/FindGStreamer.cmake</a> Here is what I have done in my cmake file. cmake_minimum_required(VERSION 2.8) project(InitGStreamer) add_executable(${PROJECT_NAME} main.cpp ) set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/Modules/") find_package(gstreamer-app REQUIRED) However, I'm getting the following output error from CMake.

CMake Error at CMakeLists.txt:5 (find_package): By not providing "Findgstreamer-app.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "gstreamer-app", but CMake did not find one. Could not find a package configuration file provided by "gstreamer-app" with any of the following names: gstreamer-appConfig.cmake gstreamer-app-config.cmake Add the installation prefix of "gstreamer-app" to CMAKE_PREFIX_PATH or set "gstreamer-app_DIR" to a directory containing one of the above files. If "gstreamer-app" provides a separate development package or SDK, be sure it has been installed. *** cmake process exited with exit code 1. THEN I changed my CMake to this. cmake_minimum_required(VERSION 2.8) project(InitGStreamer) add_executable(${PROJECT_NAME} main.cpp ) include("${CMAKE_SOURCE_DIR}/cmake/Modules/FindGStreamer.cmake") set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/Modules/") #find_package(gstreamer-app REQUIRED) find_package(PkgConfig) #aux_source_directory(. SRC_LIST) #add_executable(${PROJECT_NAME} ${SRC_LIST}) include_directories( ${GSTREAMER_INCLUDE_DIR}) add_definitions(${GSTREAMER_DEFINITIONS}) #target_link_libraries(MPEG4GStreamer ${GSTREAMER_LIBRARIES}) This seemed to do something... I didn't get any errors, but when I went back to my source code file in QT Creator, it still could not find #include <gst/gst.h>. Am I wrong to assume that QT Creator will resolve the where this header is automatically based on the cmake setup I have? <div class="moz-cite-prefix">On 10/26/2016 11:32 AM, Nicolas Dufresne wrote: </div> <blockquote cite="mid:1477506728.22468.15.camel@gmail.com" type="cite"> <pre wrap="">Le mercredi 26 octobre 2016 à 17:56 +0000, Rick Blacker a écrit : </pre> <blockquote type="cite"> <pre wrap="">I’m new to both GStreamer and CMake.

Here's an exemple: find_package(PkgConfig) pkg_check_modules(GST REQUIRED gstreamer-1.0>=1.4 gstreamer-sdp-1.0>=1.4 gstreamer-video-1.0>=1.4 gstreamer-app-1.0>=1.4) Notice that GStreamer is a collection of libraries. The list will depend on your application needs. From there you'll have to update few things. Globally, link_directories with ${GST_LIBRARY_DIRS} (only needed if you use GStreamer from non-system installation). And per target: - target_include_directories with ${GST_INCLUDE_DIRS} - target_compile_options with ${GST_CFLAGS} - target_link_libraries with ${GST_LIBRARIES} You'll also have to choose between private and public exposure depending if you create an app or library and if you expose GStreamer through your library or not. cheers, Nicolas _______________________________________________ gstreamer-devel mailing list <a moz-do-not-send="true" class="moz-txt-link-abbreviated" href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel">https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </pre> </blockquote> <fieldset class="mimeAttachmentHeader"></fieldset> <pre wrap="">_______________________________________________ gstreamer-devel mailing list <a class="moz-txt-link-abbreviated" href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a class="moz-txt-link-freetext" href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel">https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </pre> </blockquote> </body> </html>
