Revise need of pcl_apps library target

[SergioRAgostinho]

I just noticed this

pcl/apps/CMakeLists.txt

Lines 215 to 221 in 356ea4f

	set(LIB_NAME "pcl_${SUBSYS_NAME}")
	PCL_ADD_LIBRARY("${LIB_NAME}" "${SUBSYS_NAME}" ${srcs} ${impl_incs} ${incs})
	target_link_libraries("${LIB_NAME}" pcl_common pcl_io pcl_filters pcl_visualization pcl_segmentation pcl_surface pcl_features pcl_sample_consensus pcl_search)
	PCL_MAKE_PKGCONFIG("${LIB_NAME}" "${SUBSYS_NAME}" "${SUBSYS_DESC}" "" "" "" "" "")
	# Install include files
	PCL_ADD_INCLUDES("${SUBSYS_NAME}" "${SUBSYS_NAME}" ${incs})
	PCL_ADD_INCLUDES("${SUBSYS_NAME}" "${SUBSYS_NAME}/impl" ${impl_incs})

I'm inclined to replace it with regular executable targets. Currently it's compiling source files from apparently two different applications into a PCL Library "target" called pcl_apps. 😕
