Linux 使用多个库创建CMake可执行文件

我已经成功地使用CMake从源文件创建了静态库。现在我需要使用这些库创建许多可执行文件。我已经阅读了CMake示例，并试图复制它们列出的内容，但似乎不起作用。我收到错误信息：

链接CXX可执行文件.././build/bin/discoveryService armv5l-timesys-linux-uclibcgnueabi-g++:cmakfiles/discoveryService.dir/discoveryService.cpp.o:链接器输入文件未使用，因为链接未完成

下面是我的目录结构的快速概述。每个目录都从该目录中包含的源文件创建一个静态库。大多数目录还需要生成依赖633/arm目录中的库的可执行文件：

这是我的原始Makefile：

$(shell ../../build_environment.sh)

BIN = ../../build/bin
TMP = build

BUILD_DEF = -DBUILD=$(BUILD_VERSION) -DBUILD_DATE=$(BUILD_DATE)

# these files are captured from the DSPLink Sample build directory (and the named  changed)
# they contain the appropriate includes and flags to build a dsplink application.
DSPLINK_INCLUDES = $(shell cat ../dsplink_config/dsplink_includes.txt)
DSPLINK_FLAGS = $(shell cat ../dsplink_config/dsplink_flags.txt)
DSPLINK_DEFINES = $(shell cat ../dsplink_config/dsplink_defines.txt)
DSPLINK_LIBS =      $(DSPLINK_PACKAGE_DIR)/dsplink/gpp/export/BIN/Linux/OMAPL1XX/RELEASE/dsplink.lib

我使用了如中所示的ADD_可执行文件，并尝试使用TARGET_LINK_库来链接这些库。非常感谢您的帮助。

在添加可执行文件之后，是否需要目标链接库显示服务通信。。达到理想的结果请参阅函数的定义：TARGET\u LINK\u LIBRARIEStarget library1 library2。另见。还请尝试修改其他目标链接库：目标是通信。在目标链接库中，目标名称作为第一个参数丢失。请检查。
