rqt_multiplot_plugin catkin build error

[mobiiin]

hi. I followed all the instruction and installed the dependencies. still I get build error while running catkin build

Errors     << rqt_multiplot:make /home/mobiiin/catkin_ws/logs/rqt_multiplot/build.make.014.log
/usr/bin/ld: cannot find -lQWT_LIBRARIES-NOTFOUND
collect2: error: ld returned 1 exit status
make[2]: *** [/home/mobiiin/catkin_ws/devel/.private/rqt_multiplot/lib/librqt_multiplot.so] Error 1
make[1]: *** [CMakeFiles/rqt_multiplot.dir/all] Error 2
make: *** [all] Error 2

I also have all the libqwt.so* files in /usr/lib/

The problem is that QWT might have a different name on some systems.

rqt_multiplot_plugin/CMakeLists.txt

Lines 33 to 46 in 2a223fa

	if("${qt_gui_cpp_USE_QT_MAJOR_VERSION} " STREQUAL "5 ")
	find_library(
	QWT_LIBRARIES
	NAMES
	qwt-qt5
	)
	else()
	find_library(
	QWT_LIBRARIES
	NAMES
	qwt-qt4
	qwt
	)
	endif()

In my case on arch the name was "qwt5-qt5". By adding this name in the CMakeLists CMake was able to find the library and the linker was configured properly.
