1. 报错:Flow control statements are not properly nested.

1)报错内容

CMake Error at CMakeLists.txt:70 (else):

Flow control statements are not properly nested.

– Configuring incomplete, errors occurred!

2)解决方案

此错误是由于 CMake 的流控制语句(如 ifelseelseifendif)没有正确嵌套导致的。

要解决这个问题,你需要确保每个 if 语句都有相应的 endif 语句,并确保所有的 elseelseif 语句都出现在 ifendif 之间,且顺序正确。

正确的使用方法:

if(CONDITION1)
  # Do something
elseif(CONDITION2)
  # Do something else
else()
  # Do yet another thing
endif()

错误的使用方法:

if(CONDITION1)
  # Do something
else()
  # Do something else
endif()
else()
  # This else doesn't have a matching if
endif()

为了解决你的问题,请检查 CMakeLists.txt 文件,确保所有的流控制语句都正确嵌套。
