building Gstreamer mpegts project with Cmake

Question

We are trying to use Gstreamer's mpegts pluging to record a video stream stream using the following Gstreamer example code https://gstreamer.freedesktop.org/documentation/mpegtsmux/mpegtsmux.html?gi-language=c. When we compile the code using gcc mpegtstest.c -o mpegtstest `pkg-config --cflags --libs gstreamer-1.0 gstreamer-mpegts-1.0` -v everything works as expected and the program records with no issues. We are now trying to compile the code using cmake and make. cmake generates correctly but make fails with error. /usr/bin/ld: cannot find -lgstreamer-mpegts-1.0.

After searching online and trying a few different things found online like here and looking at Github code we don't know why or how to fix it. Any advice or assistance is much appreciated. thanks in advance.

Solution Thanks to nega's comment and solution, changing include_directories(${GSTREAMER-MPEGTS_INCLUDE_DIRS}) to include_directories(${GSTREAMER_MPEGTS_INCLUDE_DIRS}) worked.

Answer 1

Based on your cmake output, I'd guess that you're using a version of FindGStreamer.cmake cribbed from WebKit. If that's the case, the variable you want to use is GSTREAMER_MPEGTS_INCLUDE_DIRS. Note the lack of a hyphen in the variable name.

If that's not the case, use a simple message() statement before the use of a variable to show you its value during the cmake step.

In your CMakeLists.txt:

message("GMID: ${GSTREAMER_MPEGTS_INCLUDE_DIRS}")
include_directories(${GSTREAMER_MPEGTS_INCLUDE_DIRS})
target_link_libraries(${CMAKE_PROJECT_NAME} gstreamer-mpegts-1.0)

In your shell:

$ cmake ../src |grep -i ^gmid
GMID: /usr/local/Cellar/libffi/3.3_2/include;/usr/local/Cellar/gst-plugins-bad/1.18.3/include/gstreamer-1.0;/usr/local/Cellar/gstreamer/1.18.3/include/gstreamer-1.0;/usr/local/Cellar/glib/2.66.7/include;/usr/local/Cellar/glib/2.66.7/include/glib-2.0;/usr/local/Cellar/glib/2.66.7/lib/glib-2.0/include;/usr/local/opt/gettext/include;/usr/local/Cellar/pcre/8.44/include

Another easy debugging step is to grep the cache after running cmake.

$ grep -i ^gstream CMakeCache.txt
