CMake工具链包含多个文件

Question

由于无关的原因，我希望能够将多个文件包含到工具链文件中。假设我的工具链包含以下内容：

message(STATUS "file1 is ok")
include(./build/file2)

file2包含标识行：

message(STATUS "file2 is ok")

CMakeLists.txt包含：

cmake_minimum_required (VERSION 2.8.8)
project (pro)
message(STATUS "cmakelists.txt is ok")

我使用以下命令调用它：

cmake -DCMAKE_TOOLCHAIN_FILE=../../build/file1 ../../

现在，我希望得到以下结果：

-- file1 is ok
-- file2 is ok
-- cmakelists.txt is ok

然而我明白了：

-- file1 is ok
-- file2 is ok
-- file1 is ok
-- file2 is ok
-- The C compiler identification is Clang 5.0.0
-- The CXX compiler identification is Clang 5.0.0
-- Check for working C compiler: /usr/bin/cc
CMake Error at /fullpath/build/file1:2 (include):
  include could not find load file:

  It fails with the following output:

CMake不仅两次打印信息，还声称在此之后第三次找不到包含的文件。

有什么想法吗？

不仅cmake打印信息两次

这是正常的：在配置过程中，会执行几个步骤。在工具链文件的每一步使用。

  

它还声称在此之后第三次找不到包含的文件。有什么想法吗？

提供绝对路径。
