CMake编译过程中出现Configuring incomplete的原因

记录犯的一个低级错误。

执行基于CMake写的一个个多层包含的复杂编译脚本时，总是报下面的错误:

CMake Deprecation Warning at /usr/src/googletest/googletest/CMakeLists.txt:48 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

一下看不出嵌套的多层目录中哪个脚本有问题，折腾了一些时间，发现原来是随意犯了个严重错误，支持编译的多个库(包含头文件和so)里其中某个在编译后那些源码和cmake脚本没删掉，导致编译时里面的cmake脚本被包含调用了，里面指定的文件是临时文件编译完库后就被删掉了而不存在:

foreach(component ${config_reader_FIND_COMPONENTS})
    include(${CMAKE_CURRENT_LIST_DIR}/cr-${component}-config.cmake)
endforeach()

CMake Error at /home/fychen/libs/cr/cr-config.cmake:2 (include):

include could not find requested file:

这种非预期包含调用导致整个编译异常退出，从而Configuring incomplete发生了，Makefile没生成，将发生错误的这个库里除include和lib以外的库都删掉，然后编译整个项目就顺利完成了。
