在/source/CMakeLists.txt我有这行代码;

include_directories(jsoncpp jsonreader)

但是在build目录中运行’cmake -G“MSYS Makefile”../source’生成Makefile然后运行’make’会生成以下错误：

Scanning dependencies of target updater
[ 33%] Building CXX object bin/CMakeFiles/updater.dir/main.cpp.obj

compilation terminated.
make[2]: *** [bin/CMakeFiles/updater.dir/main.cpp.obj] Error 1
make[1]: *** [bin/CMakeFiles/updater.dir/all] Error 2

我做错了什么,我该怎么解决这个问题？
