如何在cmake中将预构建的目标文件添加到可执行文件
问题描述：
我有一个 add_custom_target 可以触发一个项目的make（该项目不使用cmake！）并生成一个目标文件。我想将此目标文件添加到项目cmake中的可执行目标中。有办法吗？
I have an add_custom_target that triggers a make for a project (that project does not use cmake!) and generates an object file. I would like to add this object file to an executable target in my project's cmake. Is there a way to do this?
答
SET(OBJS
${CMAKE_CURRENT_SOURCE_DIR}/libs/obj.o
)
ADD_EXECUTABLE(myProgram ${OBJS} <other-sources>)
SET_SOURCE_FILES_PROPERTIES(
${OBJS}
PROPERTIES
EXTERNAL_OBJECT true
GENERATED true
)
对我有用。显然，必须设置这两个属性 EXTERNAL_OBJECT 和 GENERATED 。
That worked for me. Apparently one must set these two properties, EXTERNAL_OBJECT and GENERATED.
