请问用cmake编译出现下面的情况怎么回事呢，有大佬知道的么？

make: *** [cmake_check_build_system] 错误 1

下面是我的cmakelist.txt文件

aux_source_directory(. DIR_SRCS)

get_filename_component(PARENT_DIR ${CMAKE_CURRENT_SOURCE_DIR} DIRECTORY)

string(REGEX REPLACE ".*/(.*)" "\\1" LIB_NAME ${PARENT_DIR})

if (DIR_SRCS)
    foreach(libname ${LIBNAMES})
        if (${LIB_NAME} STREQUAL ${libname})
            add_library(${libname} ${CMAKE_LIB_TYPE} ${DIR_SRCS})
        endif()
    endforeach()

else()
    message(WARNING "not find is src file!")
endif()

看看这个能不能帮助到你：cmake编译时报错：the source directory "xxx" does not exist 怎么解决

应该是你前面的变量用了 ${xxx} 去引用， cmake if语句 判断需要用引用
ex
set(MY_VAR abc)
if(MY_VAR STREQUAL abc)
message(FATAL_ERROR "I am in here")
endif()
